WETLAND FILTER | HOW TO BUILD IT
Vložit
- čas přidán 4. 08. 2019
- In this video, John Adams, owner of Modern Design Aquascaping Inc., SHOWCASES how the team builds an up-flow wetland filter, also often referred to as a bog filter, a wetland filter, or a constructed wetland. This video covers the nuts and bolts of how we build it and why. It covers the parts we use as well as how we lay out the system. The next video we do on this wetland will show the time lapse of the project going together and will show you what it looks like when it is completed. Enjoy!

Happy Pondering ;)
I love it when someone so excited about their products. This is the sign of trust.
40 minutes of info in an 8 min video, thank you so much for this!
Glad you liked it!
Best video I've seen yet that actually explains the construction details of a proper wetland filter. Thanks mate!
Glad you liked it. I plan to make more in the future!
Thanks, we plan to make more in the future!
Best video that explain that I have seen Thank you
Glad you enjoyed it!
FANTASTIC!!! Your enthusiasm for what you do is so contagious.
UhhhHuhhh- love from beach in SouthPort NC
Love your enthusiasm on camera, especially when talking about filtration!
I was sooo ready to get to work at that point.
You rock! Another great vid! Aquascape should hire you to make these vids for the training series!
I’m watching from Ecuador 🇪🇨. I’m building 5 large recreation ponds in my farm. Have been watching videos for days and these are the best material I’ve found so far. Thank you !!
That is so cool- we appreciate that we can help and inspire so many from so far away! Best of luck with your projects ;) John G
Great explanation of the wetlands. You're info is much appreciated!
My pleasure!
Wow! Thank you for the in depth explanation on the construction behind a wetland filter. Amazing that the blocks can carry so much weight.
Yes, the strength is impressive. If you add a fifth vertical entry panel it nearly doubles the crush strength! It’s all dependent on the proper installation / support though.
Great video
Thanks Ricco!
I love the energy and inspiration!
Hope it helps ya ;)
All your videos are extremely helpful! Thank you very much.
Thanks for watching!
Love your enthusiasm and the way you have explained how this is built and works 👍 so so so, want to add one of these to my pond when I make it larger next year. Thank you so much 🍻
You are officially a pond “enthusiast” (addict) 😉
Great information! I didn't think about the slopes back towards the clean out. Keep up these great videos!!
Thanks for the kind words
great job John. Love watching your informative, educational and entertaining videos.
Glad you found it fun👍🏻
Nice!
Glad you enjoyed!
I want to see a video on wetland filter maintenance - the process involved with backwashing/pumping out the snorkel and the results
I plan to shoot that next time we clean one out👍
I just love this video, it is so you LOL. And I would know🐸💙
Many thanks for uploading this video very helpful indeed 👍
More detailed video coming up in next week or 2 on the subject!
This is my new favorite video. I'm definitely subbed. Thank you so much
Stay tuned-wetland videos are next in the “Water Feature Design Series”🤠
Great video, thanks! wetland filtration is really the best choice for almost every pond. especially for reducing maintenance. aaand adding simple scheme, sketch or drawing will make such video much better :)
We did 3 videos in our water feature design series on wetland how to start to finish- Here’s the first one- Water Feature Design Series 7 | Wetland Filter Basics | Bog Filter Basics
czcams.com/video/3LMziQLaiAo/video.html
You are doing amazing job!
Thanks, glad to help ;)
Great explanation of things! That's a big hole!
A mighty big hole indeed!
Your great.
Question I have is can you do tutorial on how you plumb the wetland filter? I know the same principle is like under gravel aquarium filter.
I will go into that next time!!
Such a great video, very informational yet straight to the point.
Love ya Nickers, we are going to rule the world❤️❤️❤️❤️❤️❤️❤️
I don’t think I’ve laughed as much with/at you in any of your other videos! Very advanced information but I do enjoy your energy and the way you talk about what’s going on. I look forward to meeting you at pondo!
See you at Pondo😎
....well I was supposed to be packing up for Florida but I'm never going to skip over this video that started playing on my screen lol
Thanks for hanging with us!!
This guy is working too hard.... He needs a vacation and cold beer?!! Lol I respect it though! I want to build a wetlands filter one day!!
It’s a tough job for sure. We are currently working with a team on a 12 day project and after 10 days I feel like I have been in a car crash. Respect to my mates and their work ethic!
Great detail on this one, another great video! Go pop!
Thanks for helping me dig this monstrosity of a filter!
thnx so much for this film its helped heaps
Glad to help, it’s so fun to share!
Hi, great video. Please can you post a link to your time lapse of the construction, as I couldn't find it on your Channel? Thanks
Never made that one.. Should I?
Great info !!!!
The one that came out today is better👍🏻
Great vid mate, I've just recommended it to some UK koi guys on here
Thanks, we appreciate you, let us know if there’s anything in particular you would like to have some content about. Right now we are just covering projects👍🏻
@@KoiAddiction If you can I would like to see detail on what height you guys like to set the water level at within the wetland and at what height you like it to flow out at the waterfall exit from the wetland
Keep up the great work guys!
Nice job buddy 👍
Thanks Nick, hope to chat with ya soon? Have a great week ;)

Welcome
Great Video, Thank You. Id like to use Plastic drums full of holes, to replace Aqua Blocks. AquaBlocks are very expensive. Would that cause any problems? I used them in a different Pondless storage pond. They seem to work great. Any Thoughts?
Thanks
I am sure that there are other ways of doing it, I can’t say what the structural stability will be or how effective you will be when it comes time to clean it. Let me know what you learn!
Hi John, I see you use 2 layers of geo textile for the bog...one below and the other one above the EPDM liner. Could you also use 2 layers in the pond in order to extend and protect the EPDM? Or would this create some problems? Thanks for your help!!!!
We typically use 2 layers under sharp stones or med boulders for added protection. If you really want protection, use Aquascape’s rock pad. It is expensive but well worth the $$ if conditions are tough. I believe that we are covering the liner to make it look natural and beautiful. In the process we are also blocking out the UV rays which will surely extend the life of the liner. I have worked on ponds that were over 20 years old with EPDM liners that were covered in stone and the liners were still strong and pliable like new👍🏻
Hey John. Great videos, thanks for all the information. Do you have a video on backflushing an aquascape wetland filter? Would be great to see how it's done.
No but I will make one in the spring time!
How do you calculate the water flow that should be pumped inside the centipede?
I shoot for 1500-2000 gallons per hour per centipede. Best to set it up with a ball valve style bleeder on the feed line. That way if flow is too fast in filter you can let more loose up top and slow the wetland down👍🏻
Please provide more indetailed instructions on installing a wetland filter
Just did 3 videos in my Water Feature Design Series on wetlands, check them out in the playlist👍
Hey John, great video series, wanted to ask, is there a limit in water height above the last gravel? I mean in the water where the plants will be? Can I it be 12” of water?
Yes, sorry I missed this question. Go as deep as you like, no worries ;)
Your videos are very informative and helpful. I just rescued a 6-year-old red eared slider turtle and we plan to build it a nice pond in the back yard. Here is the deal, we live in Phoenix, Arizona and the heat in the summer can be shockingly high (121 degrees at times). How deep do I need to dig the pond to ensure the water stays cool enough for the turtle? Also, does the depth of the pond the heat impact the filtration system design? If so, how?
I have a feeling in your kind of heat that 3 feet deep isn’t going to make a significant difference over 2 feet deep. The important thing would be that you create some shade. Shade in the pond is in like a fish cave and also a shady place outside the pond Where your turtle can rest. I would suggest investigating what type of habitat turtles live in in your area, and then do your best to replicate that. As far as filtration, I haven’t had any ponds get hot enough to have a negative impact on the beneficial bacteria, only cold. Thanks for hanging out with us on our channel 😎👍
Going to build a small pond in the back yard. Should I stick with a traditional skimmer /waterfall system or should I build something like this on a smaller scale.
How big is your “small pond” going to be?
Shooting for 6x10x3-3.5.
Hello John, I have a question about calculating amount of gravel for Wetland. For example, if I have a case of a 7 feet by 7 feet wetland, approximately how many tons would be needed, let's say for a uniform size of 1-inch gravel? Thanks...
What size pond was this for and can you run the pump over winter in cold weather freezing conditions? I have a 50x75 swimming pond i want to try a bog filter on. Any suggestions? Size? Pump size? Amount of snorkels?
Very well put together video ! Couldn't be better! Thank you for sharing!!!! Keep up the great work and drink some water while you talk would y'all hahah
I'm building a small/medium size koi pong behind my yard....approx 10ftx10ft. Where would I go get something like the wetland filters system to build it? Please let me know. Thank you.
Google aquascape inc pond supplies near me! Or call them in Chicago direct!
@@KoiAddiction thank you so much ! I sure will!
Great video! I heard the aqua blocks and snorkel are expensive. Is there a way to build your own?
They are and you can. I personally don’t want to re-create the wheel but a person working on their own system could get creative!
Love this and would love to add this to my pond. I live in Illinois what do you with bog filter in the winter months?
Drain the lines and leave it full until spring, that simple👍
Hello John, I have a question: Do you recommend using pea gravel for the top layer in a wetland filter? If not, could you explain why? I've never seen you guys do it in any of your videos. Thanks...
We used to and we don’t anymore. Clogs up rapidly and it is very difficult to clean. The spaces between the P gravel are so small that it’s just not easy to do maintenance side. Three-quarter inch gravel is the smallest that we use anymore.
Do you prefer the centipede+snorkel vault to lay parallel to the pond or perpendicular?
It is based on layout of the wetland- does not matter to me, just how we design it each time based on layout in a space!
I am having trouble figuring out the GPH that can go through the upflow filter. how do you calculate the size of the filter with the flow you ned for the whole system?
We have 4 wetland videos in the playlist Water Feature Design Series. The last 3 should answer all of your questions (especially #7.1)
You do Awesome work. I'm very inspired.
My pond will 440 sq. ft., so I plan to build a 110 sq.ft. wetland filter. How many aquablox should I use?
Aquascape has a standard 120 S.F. design that they can send you a pdf design for. That one uses 32 small blocks, 2 centipede modules, and a max flow of 4000 GPH. If you call tech support at Aquascape Inc. in Saint Charles, IL.-> they will email you the schematic FOR FREE 😎
Now I understand how this filter works, I have a dry pond on my property that I’d like to stock to have myself a fishing pond can this be done without all the decorative rocks ?
I guess, but I would do it differently. Probably another video topic :)
Hi John G. Adams,
Brilliant information.
Please can you advise on the following. I would like to know if a bog filter would be as effective being used the reverse way. What I mean is if the pond water level was slightly higher that the bog filters water level, as in a spill way. Then the bog filters water is pumped up into the pond on opposite side.
Yes, I have put them in a pond and they work just fine! Fancy jets! I just designed one in Knoxville in fact :)
I'm hot and exhausted just watching this video 😁 As a fat guy, when we do move down that way, I fear the summer like never before. I might have to talk the wife into a rec-pond instead of the 10x14 🤣😂🤣
I hope she’s on board for that! I’m not so skinny myself these days...just sayin
First off well done on the vid! Okay it's my house that I'm making a lazy river around my pool. My wife won't swim with the fish that I'm putting in the lazy river. So I have to put two systems, one for the pool and one for the "fish" in the lazy river. 25000 gal for the pool and 27000 gal for the lazy river how many aqua block would I need? I have about a 6foot Width for both systems how long should they be?
Wow that’s a big undertaking! The typical size for wetlands is 25-30% of the surface area of the pond. That should get you started! Aquascapes has CAD drawings for layouts available once you decide how big you need to go! Thanks for watching ;)
Very informative explanation. I'm tired just watching it.
Lol, its alot of work🙄
Hey John! I am in the process of upgrading to the Aquascape Lifestyle and I am in the process of constructing a Wetlands Filter and a negative edge or an intake bay. That leads to my question. Which would you prefer for Zone 6 where I could possibly run all year long if it matters? I have watched your video on both but didn’t know if there was an issue with Winter conditions? Love the videos man!! These are a HUGE HELP for pond owner upgrading their own systems! Thanks so much!!
I’m doing negative edge at my house- more expensive but better result! Ice no worries, just make sure to keep extra “free board” on the negative edge area so it can handle some ice. If you plan on running it all year that is ;) Good luck with the project!
Is there a calculation for how large the filter has to be based on acre ft of pond?
We do as close to 10% as possible up to about an acre. At that point I can even dial it down more closer to 7%. It really depends a lot on the body of water, amount of runoff, quality of runoff, etc. And huge features sometimes it just makes sense to have two intakes and two wetlands for circulation purposes. At that point, you can start out with a minimal filter and then base designs on results.
Brilliant video but I have a question if you put the smaller stones on the top & biggest on the bottom how do the bigger bits of crud get through the smaller ones please?
They do not. The particles are captured and digested by the biological filter. Large chunks are captured by the pre-filter and the rest are removed by annual back-flushing of the filter system!
@@KoiAddiction Ahh makes sense so would I need 2 pumps to build this as I only have 1 at the opposite end to my waterfall
slooooooooooowwwww dddoooowwwwnnnnnnnnnnn
🤣In Motown?
Couldn't find the time lapse video :-/
I’m working on it, I have a girl working on a video about the project in its totality and I am also working on creating a time lapse of the wetland filter. You just have to have patience, I have so much content we are building faster than I can edit😂😂 I really appreciate you watching!
@@KoiAddiction I was a great video.... Thanks for the reply. I look forward to seeing the rest. You guys have so much fun doing what you do. Thank you for your efforts!!! Signed, ~Patiently Waiting~ LOL
I'm also waiting for it. Great work!
Im waiting too
Great video, thank you! Also curious about the details of the intake bay for this project, assuming there will be one :)
That will be in a few videos from now!
@@KoiAddiction Looking forward to that :)
Hey John running my power supply to the Pond buddy recommended putting a underground box but I noticed on our pond videos it’s always stubbed up out of the ground does it matter which way or is there a reason for not using the underground box thanks for your info
We tried underground and never had anything but problems. I’m sure it can be done properly but I have not experienced that yet and I am no electrician so I am always at the mercy of the guys hooking up the power.
Would this idea work with a 3 or 4 inch perforated pipe ?
It is possible- I stick with my tested methods- its so much labor and materials, it isnt worth risking it to me. I feel no need to re-invent the wheel ;)
When feeding the centipede do you run the feed line through the liner then to the centipede with bulk head fittings or do you run the hose over the edge of the liner and how do you hide the inlet hose ? Looking to add wetland filtration to my existing pond . I really don't want to go through the liner with bulk head . Have watched many videos but it's never shown .
I go over. Always avoid making a hole in thhe liner when possible.
Great explanation and thanks for the info, well done. Quick ? I have a half acre canal and wondering can the wetland filter be combined with intake bay? So you only need to use one set of centipede, snorkel, aqua blocks?
Mechanical and biological filters work better for me when separated. Intake should be a good bit smaller than the wetland though...
@@KoiAddiction thanks John for quick reply, you’ve given me a lot to think about. Watching all your clips now and wish you all the best success in your endeavors, you seem like a good honest bloke.
Do you dig your initial hole 5' deep? Do you put a snorkel extension on top of what you show in the video? How much water do you allow above the rock? Do you ever feel the need to put drainage underneath the filter to carry away ground waterer do you feel that the filter is heavy enough that groundwater will not become an issue?
Yes its 5 feet deep. Snorkel extension not usually needed (not used in my video), ground water is addressed if necessary, if you think it is an issue be sure to let it out!!
@@KoiAddiction Do you have 6" of standing water & 3" of moving water above the gravel in the filter?
Hi John,a question,can we use aggregate stone or crushed stone in wetland filter/pond bottom?it is safe for fish?
I mean using crushed stone to replace river stone in wetland filter
The round stone is important because it has better inter-spacial ratios. The spaces between the stone are greater as they do not lock so tightly together. I also think that the smoothness of the round stones keeps them from getting impacted with debris-it will clean easier when you back flush it to clean it. The type of stone you choose may also be important. Be sure the the type of rock you select will not have an adverse effect on your water chemistry. IE- some limestone may be problematic for your water by increasing the Ph and creating more algae.
Hi John
We love to see ur stuff.
We ar building on a 132.000 Liters koi pond atm. And ar thinking that we ar gona build a wetland filter..
Do u have any calculation on how big a filter we need to build..
Bedst regards J Petersen
Denmark
I start at 30% of the pond size for the wetland. I have done less. The larger the pond, the smaller the % becomes.Anything is better than nothing! You can start small with future expansions, just plan for it in your intake design so it can handle the add on later!
missing ya buddy!
CZcams, how are you? I’m just getting ready to start on my Australia video today :-) thinking of you guys too. Catch up with me on messenger? I would like to hear how you’re doing👍🏻
Friend my business page Modern Design Aquascaping on facebook. I tried to tag you in the video I just put out and couldn’t.
Hey John, Great video. I'm currently in the process of building a large swim pond approximately 20x40. The deepest point about 8 ft deep and average depth probably about 4 ft. How do you size a wetland filter? And what is the water calculation for how much flow you need for the wetland filter? How many gph? I have a snorkel and centipede and eight small aqua blocks. I was thinking about buying a second centipede and using 16 large aqua blocks for the wetland filter and using the eight small aqua blocks for the negative edge intake bay. Loved your video on that by the way. Just wondering if you can give me some helpful tips so I get this right the first time and I can finish this project before the end of the summer. Thank you!
We go 30% of surface area of the pond on small rec pond filters (about 250 SF for yours). The flow rate should be 1500-2000 gallons per centipede. Good luck on your project!
Hi Jon, great videos! I m planning to build a 25000 gallons recreation/koy pond with roughly 40 ft x 15 ft surface area. The space available for the bog is long and narrow 50ft x 10 ft. My question is do you think the size of the bog is big enough for the pond I m planning to build? And how many times per hour should the entire volume of water of the pond pass through the bog filter? Does a narrow/long bog create potential problems I.e. water not circulating correctly inside of the bog? Sorry for all these questions hope you can help....congrats again for your great work and videos!!! Take care...
The answer is yes, you have enough room, shape isn’t restrictive to the function of your filter. I would do at least 10’x20’ wetland (minimum) and more is always better. You can look to Aquascape Inc. For design help and parts supply. Good luck with your project! Watch our next video, it will show the actual construction of our filter👍🏻
Modern Design Aquascaping Inc. thanks! So how many times per hour should the entire volume of water go through the bog? I find very different opinions online. Some say at least once per hour while others once every 3 or 4 hours.... lemme know what you think would be best... thanks again
Ideally 1/2 to two times per hour - but actual flow Is based on the size of the filter not the size of the pond. So if you want to reverse engineer that , the bigger the pond the less recirculation per hour that the water should be pumped through the filter-ex A small pond may be filtered twice per hour , a medium to large pond may be filtered one time per hour, very large pond might be filtered even less....
@@federiconaef5819 Contact time is important for the beneficial bacteria to go to work, for me I'd look to turnover the water column around once every 2 hours or maybe a bit less but with all these things everyone has a different opinion / feel for things
very informative video. i have one question what is the input for the centipede ? is it the same water coming from the pump of the skimmer ?
Yessir, water from skimmer, intake bay or negative edge pumps into the centipede!
i am planning to build a big fish pond,,,, but currently im not in the US,,,, but there is one only thing that concerns me,,,,, what about snakes ??? arent ponds a good habitat for snakes ??? especially between the rocks,,,,,, what do you think about that sir. because sometimes someone could swim in the pond or put his legs.. isnt that dangerous ? and thank you so much
So the caterpillar is fed with a water pump flowing into it? Is there any need for an air pump system to be installed as well or does all the rocks create the air when filtering? lastly the pond in your video, there is an enormous amount of 3 sizes of rocks probably totaling almost around 90cm deep that sits on the boxes, my point is, its a very shallow pond of around 50cm deep no for such a shallow pond?
Yes centipede fed by pump in upflow system. Aeration is always good- can never have too much oxygenation. Can be installed in the wetland if you like. Pond depth in wetland isn’t an issue. We have 6” up to 6’ of water above the wetland filter. As long as the oxygen levels are good it’s not an issue. We rarely put the wetland in the bottom of the actual pond itsself!
@@KoiAddiction thanks for the reply. I will be building probably for my client a 20mtr x15 mtr pond /pool with rock scapes as i am a artificial rock sculptor, this is something i have wanted to do for years now. i get in contact with you for the materials needed soon.
I'm building my 1st swim pond after building numerous koi ponds. I want to do a wetlands as well as an intake on this 18 by 22' swim pond. Issue in having is he is going to put pavers around it and a screen enclosure. Therefore I am limited to my outside space because of variances on the screen enclosure. I'm able to fit in the intake but the wetlands will not fit Inside the enclosure. I was thinking of doing a 6000 series bio falls. Then I was thinking adding 3 centipedes snorkel and aqua blocks on the bottom of the pond with a 4 to 6000 pump pumping water up or into the centipedes and up into the pond to cool the water off. Do you think this is a good option or do you have a suggestion? Again my issue is not enough space for a wetlands but I would like to add some to the bottom of the pond and I've already purchased the centipedes and snorkel so I would like to use them and again and thinking of using them in the bottom of the pond covering them with gravel and then some flagging with gravel between. I just want to make sure this thing is filtered properly because they are going to house fish and they are going to swim in it. Thanks for any help you can provide.
Yes that will work! I have friends who have done that very thing with success. IT MAKES FOR A MUCH DEEPER EXCAVATION! Don’t forget to figure all of that with pond under-drain before the liner and you may hit water table so be ready for that. Would it be possible to locate the wetland outside and let the water flow back in through a pipe wrapped in liner?
@@KoiAddiction no room unfortunately. We do have next to waterfall area about 4x8 foot. Maybe use 2 centipedea inside the bottom of the pond and one and a half centipedes in a small 4x8 wetlands next to biofalls 6000?
Can I combine a wetland and a waterfall feature all in one flow with one pump? I was thinking to pump water up through to a bog filter area which is few feet above pond level and the runoff from that goes down a rocky channel over a waterfall back to the pond.
Second, does a wetland area need a pump or can it simply be a region on the outskirts of a pond (as in nature)? I wish to avoid multiple pumps if at all possible
You can combine pumps BUT pump redundancy is a safety net. If you only have 1 pump and (when) it stops you are dead in the water. If you split the flow in 1/2 you will still be OK while you fix the issues!
@@KoiAddiction Good thinking but what do you mean "dead in the water"? Pump will just be working to keep the water transparent/pleasant to look at :) Not exactly threatening any lives by stopping for a time while I replace the pump.
Hey John, I'm looking at making a stream with a "mini" wetland at the begining. I'm talking 4 small aquablox. Is there a way of doing this without using a centapede and snorkle? Can the flex pipe just be plumbed into the aquablox or am I asking for trouble? This will be a long stream, but no fish.
I would use a pondless vault at least-that will give you a way to clean the filter (low point with access). Pump the water in the bottom of the vault. This is Not the “ideal” inlet but as long as the water is being pushed up through blocks it will help filter. The velocity of water at that point may push water out of the top of the vault as pressure builds from sedimentation so dont put it on the edge of the liner AND the flow rate will be faster than ideal so I wouldn’t expect much de-sedimentation (that doesnt even look like a real word 🤣). Good,luck & consider a bio-falls filter!
@@KoiAddiction thanks very much for the reply. You've confirmed my worries of sediment buildup. I was envisioning spillways bowls in a raised area to start the stream because the area is completely flat. That was the only reason for the aquablox. I was picturing water coming up around the spillways bowls rather than water flowing around them. But this leaves a very large stream with zero filtration and no way to removed sediment. The stream I'm quoting will be approx. 125' and in full sun. Can you think of any pitfalls I may run into? This is my first quote, I'm worried I'm over thinking it. I've even done a conceptual drawing to give them an idea, even though I know that's not recommended. Thanks again John.
Honestly just make sure you design the reservoir to be big enough to capture your water in motion, that is the most common mistake people make is under sizing the reservoir. Other than that obviously weather can be a factor on a large project and do you want to use big rocks and a feature of that size.I would recommend using Numbers for my smaller project to get accurate stone quantities and man hours so your bid is good, and profitable! Don’t forget to add in cleanup time, typically one day of cleanup per week of on-site work. Let me know if I can help you out!
@@KoiAddiction once again, thank you. The aquascape community seems to be so helpful. Yeah if you want to help I'm not far away from you, just eastern Canada. Lol. Seriously though, I appreciate your willingness to take the time to answer my specific questions. Never thought of cleanup time being part of billing hours, and I can see how it would be a lot of lost time if I didn't include it into the quote. I'll let you know how I make out. Cheers
Hey John....great videos! It was about time someone started making technical videos about ponds construction! I m thinking of building a 500 sqft pond 6 feet deep with a large bog and a negative edge. I am also thinking of having under gravel suction system for the bottom of the pond. Do you think this could be beneficial? My goal is to have amazing water quality... lemme know your thoughts...keep up the good work!
I have mixed feelings. While the under gravel system makes sense, I personally prefer to use jets in the pond for lower circulation. I have seen people use the pond bottom as the up-flow wetland. I have also seen the bottom used for suction. In a rock and gravel pond, I just like to push water up from bottom if anything because it is harder to clean if it pulls debris to the bottom you have to drain pond or swim to service. If you’re just looking for better circulation, I would do a simple up-flow system and/or jets. The separate wetland allows for filter cleaning independently of the pond, that’s always nice! Have a great day👍🏻😎👍🏻
Hey John, just wondering how difficult it would be to use solar for the pumps?
You just need to convert solar to line-voltage and then run normal pumps. I have never seen a great solar pump but solar power could def run high-efficiency electrical pumps ;)
Hi John, Great fan of your videos and this one was of particular use as I am going to for a wetland filter for the pond that I have inherited.
Unfortunately here in the UK we have a massive problem sourcing rounded river type rock especially of the sizes you (and Aquascapes) recommend. What alternatives can I use? I did even think about using the Aqua blocks throughout and filling each layer with different sized media balls but this is MASSIVELY expensive! Any help you can give would be greatly appreciated! Mark
The reason the angular stone isn’t as good is because it’s harder to back-flush debris since it get’s locked in tighter in the filter bed. I have used angular stone in the past- it’s just not preferred. If you can’t get it use the other- you’ll just want to clean it more often. Skip the small gravel if its angular as well. You need the stone to maintain spaces in between for debris and water flow. Can you get smaller rounded stones or none at all?
@@KoiAddiction Thanks so much for taking the time to reply! 😊 👌 We have issues getting river rock here so I think I will have to go with clean crushed rock for the bigger stuff and then use rounded as soon after that as I can, then clean out a little more often as you suggested. Keep up the good work and your infectious enthusiasm!!! Also, thanks for all the Water in Motion info you have broadcast, simple to understand, very informative and a big eye opener! When are you guys coming to the UK to teach us how pond work SHOULD be done?
The centipedes are cleanable but how do you clean the debris that sinks to the bottom outside of the centipedes?
We have a video on our channel on how we clean a wetland👍
@@KoiAddiction 🙏
I am just a guy wanting to put an 11 by 16 pond with a stream and fall in my yard. The more I have watched video and talked with installers the more suspect I am. They have made it sound like the bio=falls won't be enough. The gigantic hole to be dug for these wetland filters seems ridiculous and I wonder how safe it is to put this near the foundation of your home.
Can you link the time lapse of this full project? I wasn't able to find it in your playlists. Thanks.
Haven’t done that yet👍🏻
@@KoiAddiction Well that explains it. Thanks!
How do you know how big of a bog filter you need for a pond?
Aquascape has some “general guidelines” set out in their catalog (Google It). Then I “tweak” the formula based on effecting conditions, etc. LIke runoff, depth of pond, intended use, importance of clarity & quality.
The water going into the centipede module through the pipe , where is that coming from? Is that the line that supply’s water to the pond ?
The water in the centipede module is coming from the pond pump. It has been pretty filtered and pumped up from whatever style mechanical filter you have working in your feature👍🏻
Great, thank you, can the snorkel cap be just a little under the water level so we would not be able to see the cap ?
love this video. Its hard to find good information about an upflow wetland filter. I'll be constructing mine this summer. The pond is already dug, I just have to wait for the water table to drop. And I'm still looking for a good alternative for the centipede. They are hard to come by in Europe. What kind of pumps do you guys use? The downside of a up-flow filter is that the pumps get more debris in them.
We use many types- the efficiency of your pre-filter will keep the up-flow clean. We still do annual cleanout on our wetlands though. The pond advisor in the UK can get you your parts probably!
Question for you about insects and a wetland filter: do they enable mosquitos to thrive? I would think so if the water is only at a trickle bubbling up and then overflowing out. I'm designing an addition to our pond and want to incorporate a wetland filter, but I was thinking of using a similar system to yours pumping the intake from the bottom but also having a stream run across the top of the wetland at a slow rate of maybe 500 gallons per hour to keep the surface water flowing and keep away mosquitos as best I can. The intake water would still work its way up slowly through the media but then be swept away quickly by the stream. Do you have any input about mosquitos in a wetland filter or if there is a drawback to running a slow stream across the top of the wetland? Thanks.
I have not had any issues with mosquitos but running additional water out on top of the wetland is a common practice for us. It doesn’t affect the performance of the filter and it also enhances the return flowing waterfall into the pond!!
@@KoiAddiction Thanks for the feedback and videos.
Did you ever make a time lapse video? Another question I have, have you ever sprayed polyurea as a liner?
No time lapse video yet-nopey on spray liner. Always used the rpll-out stuff😎
I can’t find the next video in the series. What’s it’s title please?
I started a new series and did 3 parts in the water feature design series (Start to finish wetland filter) Water Feature Design Series 7 | Wetland Filter Basics | Bog Filter Basics
Hi John how do I get a hold of you? I have questions about a bill I need your help. Maybe I can pay you a consulting fee?
865-995-1234 Nina will set you up a consultation call here in a few weeks when I get back to Tennessee!
I have a 10,000 sqft swimming pond that I want to drain, clean muck off the bottom, that build a bio filter so the pond water stays clean.
Where can I find the math formulas to know how big the filter area needs to be?
Just reach out to Aquascapes tech department, they will help you design it!

Hello John , congrats on your wonderful videos. I have a question that never gets discussed. How do we calculate the correct amount of water that should travel through a bog filter per hour? I am planning to build my pond with a surface area of about 600 sqft and depth of around 6 feet. I want to have a very large bog of about the same size of the pond approx 500sqft. I will have about 5-10 koi fish. Also the bottom of the pond will have gravel and water will pumped through the gravel up flow. I would like to know how how much water per hour I should pump through the pond and how much through the up flow system on bottom of the pond. I never found anybody that discussed this topic....glad to hear your input.
When using 2 feet two 2 1/2 feet of aggregate above my centipede modules, between 1000 and 1500 gallons per hour per centipede is my target flow rate. I think the upflow from the bottom of the pond would be Relevant to the purpose you were trying to serve. If you want to use it to keep it stirred up a higher flow rate would do the trick but I would consider what effect that would have up on your thermoclines in the winter if you’re in a cold environment. If you want to know more on that I have a friend that did that system in the bottom of his pond, I can get you more detailed info.
It seems to me that the aqua blocks are not actually required for the wetland filter to work. Nor or they required to clean the wetland filter.
I have a large pond I am building a wetland filter for. If I purchased enough for 30% wetland size to pond size, there would be thousands of Aqua blocks needed for the project.
I agree they store water great, but they seem like an expense that could be cut from a large wetland filter.
What if you have limestone bedrock at the surface?
We build up. Did that once in Crossville, TN. We put down 2-3” of soft soil and built up with soil and rocks. Different - more work- still awesome!
@@KoiAddiction Thanks for the reply! I am linking a video of my place. I want to put a pool to catch all this water for swimming and watering a garden. Maybe even line up to the house for one long waterfall? The ground drains tooooo well in this limestone. It really only does what it's doing in the video when it rains heavy and other than that it's pretty dry drainage bed. Am I crazy or is something like that doable? Thanks in advance! czcams.com/video/8vYtwbtSycs/video.html
what is the purpose and function of this filter to constructed wetland
To remove organic contaminants and purify water naturally :-)
@@KoiAddiction THANK YOU
where is the second part of this video?
Thats it for that one!
@@KoiAddiction you don’t have a video of the completed farm pond project? I wanted to see intake, wetland filter and waterfall all tied together 😞
Why does everyone use centipede? Couldn’t pvc work?
Sure, you can use whatever you like- but why would I want to reinvent the wheel?
where is the intake bay vid?
