- This is part 2 of my dream pond build. In this video i started construction on one of the large bog filters. This is a total DIY project. Im trying some new things and using things i learnt from building my other ponds. This should be a fun project that hopefully results in a stunning, easy to maintain backyard (or in this case frontward) pond.

Over the last two plus years I've been in communication with Kev. Always responsive, acurate, patient, and a joy to deal with.
At times I was ready to give up. He encouraged me and today I have a spectacular bog pond and main pond with clear water and happy, healthy fish.
I wanted to say thank you to Kev. He really made all the difference including explaining that my Koi and Gold Fish love eating duckweed. I no longer buy fish food and to think I used to stress over getting it all skimmed out.
Thank you, Thank you, Thank you Kev.
Your biggest fan from East Texas,

Thanks for your kind words Lynnda. I’m really happy for you. 👍
Just made something similar for my tiny pond (it’s gonna be bigger next year). The pond is several years old with plenty of “gunk”, but I never seen the bottom of it.
Got hold of a 1 m3 Schütz IBC tank and filled it with leca. The water going in is distributed through pvc pipes on the whole bottom area. Overflow back to the pond in the top.
After just two days the water is crystal clear!!! 🎉😊 it’s really amazing! Thank you 🙏
Currently the bog filter is seriously oversized. It’s 2x the pond volume, but we’re planning on expanding the pond to 5x the filter volume.
Great to hear 😊👍
Great video! 👍😀 I will start building my pond with a large wetland/bog filter as soon as spring comes here in Sweden.
Awesome 😎
Great video and doggo. Looking forward to more on this project.
Me too. But my back is killing me! 😂
I have been researching building ponds on and off for a couple of years. You have, by far, the best videos and I want to emulate your system. My area to work in is pretty much exactly the same size you have built. Please provide measurements for the bog filter holes, intake holes, and stream. Also if you could let me know the size of the liner necessary for everything since I will need to purchase all liners. There is a sale over the next couple of days with extra 15% off so I am hoping you reply before the sale is over.
Awesome information! Thank you for sharing. I am sure I will have more questions. If you have an alternate way we can communicate please let me know.
On my website I have a downloadable pdf ($10 Aussie Dollars), it has all the formulas I use when building my ponds.
ozponds.com/pond-equipment/
Nice! Your filter looks exactly like initial version of an Aquascape constructed wetland before matrix was added))
Yeap. But much, much cheaper. In Australia the centipede costs around $900 and the pump vault another $900. I spent under $50. 🤞fingers crossed it all works. I’m also not adding any aquablox they are $50 per block, I want to experiment to see if it makes a difference.
@@Ozponds instead of aquablox it is possible to use used plastic pallets
It’s worth a shot. Initially I thought I’d use milk crates, but couldn’t source any second hand ones locally and the freight made them just as expensive as aquablox. I’ll use the aquablox in the other filter so I can compare the difference.
@@Ozponds I plan to take used plastic pallets, here they cost 3-5$ each and the size is 1.1x1.1x0.12 m. It seems perfect for me.
That’s genius. I’ve gotta look into that! Thanks for the tip 👍
The drum filter is the most effective, given that it does not need to be cleaned. It has automatic smart cleaning, and good filters have emergency systems and a system that can work without electricity for several hours; when electricity is supplied, the filter turns on and continues its work without any problems.
Your name suggests you might, possibly be biased.
I make custom drum filters of different sizes and designs, but I understand this a little.
How do you incorporate it into the landscape? Or do I need to build a special filter house to hide it?
I love the ingenuity and appreciate you taking the time to post your videos, and I have some comments for thought. I'm designing a bog for our pond expansion and will incorporate your use of the pickle barrel since I can source them locally for about $35 USD. Great use of those in your build. I'm using such a barrel to build a skimmer similar to the Helix and should be able to for under $100 USD including the floating weir and basket.
The pitfall I see with your design that I'm curious to hear from you about is the water flow. With the intake running down vertically and then 90-ing at the bottom, and with the end of the corrugated half-pipe open, I doubt intake water will ever make its way through the length of the corrugated pipe. Since water flows via the path of least resistance, it will leave the intake and, rather than struggling to pressurize (though very low pressure) the corrugated pipe cavity and going through the small holes, it will simply turn straight up and out the open end of the corrugated pipe. The water flow will concentrate just above the intake to where the vast majority of bacteria and plants will not receive equal distribution of the waste. I think if you were to say dye the water, you'd only see the dye just above the intake and not distributed up through the bog. In the event you ever retrofit or have issues, I think capping the end of the corrugated pipe and then running the intake schedule 40 pipe with holes drilled in it and a cap on the end horizontally through the entire corrugated pipe will better distribute the waste and force it through the corrugated holes and up through the media.
All valid questions. Because the water takes so long to fill the area it distributes evenly. If the water was still under pressure say if the bog was to small yes what your saying would cause problems. You can see when in other videos when I turned the pump in for the first time the water came up very evenly. It’s also funny you’ve mentioned dye I just recently added some. I wish I took footage but I added it where the pumps are located and it was awesome to see how even it distributed throughout both bogs. For me the corrugated pipe was just for solid waste to accumulate not so much as a manifold to disperse water. Either way the cool thing about documenting stuff like this is in the future me and all the people following along can see what worked and what didn’t. Hope your build turns out awesome 👍 if you are documenting it feel free to post a link so others can follow along 👍
@@Ozponds Great feedback on how the system is working in practice. The corrugated channel is definitely wise for spring clean-out. A lot of designs just have a schedule 40 intake manifold buried in rock/gravel, which I don't like since eventually the bottom will get full of muck. I'm going to be building my own skimmer and waterfall spillways, so I'll try and document them and post. Keep up the good work.
1:43 I guess without having any matrix blocks to create a false bottom it means it’ll clog up quicker than with blocks because there is less space for sentiment to sit and accumulate but it’ll still do a great job at filtering the water compared to a small sponge filter.
Time will tell. I’m the guinea pig 😉
I think it would depend on how turbulent and fast the water flow is, if it’s slow and steady the crud will settle, if it’s not then it’ll push up into the rocks and block it up.
@@jonnotuckster8856 yeah definitely would depend on the flow of the water.
@@jenson1569updates from 2 years? What's the verdict?
would love to see a follow up on the finished product
You can. Dream pond update| Summer
czcams.com/video/3x6eGnMQk5A/video.html you’ll also see it in lots of my other videos 👍
Very nice...Love it!
i didnt watch this video before comenting on the other ones about the bog x) now i know what was confusing me is the cleaning barrel. i couldnt understand the role of it on the build, i thought u had one pipe coming from the bay to the barrel and another pipe doing smth else inside the tunnel to another place and that the barrel had 2 holes, one for water entry and another for the water to go through and then downstream back to the pond. now i see that the pipe is in the tunnel that has holes in it, so the water flows throught, then the big rocks, small rocks, pebbles slowing down the flow with all the bacteria in between and then the supportive bacteria on the way downstream plus plants and algae. the barrel is simply for cleaning the bog. what i can't understand is how u use the barrel and another pump? to clean the bog x) i'm actually getting a small office aquarium for myself and start learning how to manage the nitrogen cicle and enjoy some aquascaping. but the idea i had in mind for the pond is getting clearer and actually more awesome
The barrel just allows a what I call a sump pump to be placed inside. This can then completely empty the filter. That water is great for the garden. There is a video in this build playlist where I put a pump into the barrel I can’t remember which one.
Thank you
😊👍
If you had the possibility of installing an up-flow aquascape type filter with a valve at the bottom for flushing instead of needing a vac pump, would this be a better option?
Like my bog in a barrel design? It’s a good option. Eliminates the need for a cleanout port.
Great video man !! I am adding bog filter to my pond this video will sure help . Is there rule for for how big of a pump to use for bog filter?
Nothing concrete. It’s best if the water travels slowly through the bog itself. I have a video on the flow rates you should check out. If you want to have a decent waterfall or stream you need to oversized the pump. I talk about that in a recent video (pond mistakes). Basically slow water moves up through the bog to allow solid materials to settle in the bottom. If you need extra flow for a nice waterfall or stream you can direct the excess water over the surface of the bog. Adjustable flow pumps certainly make dialling in the perfect flow much easier. Hope that helps 👍
@@Ozponds Thank You for the reply man I also wanted to ask if you tested the filter and if the cleanup drum is going to fill with water faster than the rest of the filter and over flow ?? I am planning to build exact same filter.
Yeap I’ve currently got one of the filters running. Water fills up in the bog nice and even. There’s a video when I filled it up for the first time I think it was last weeks vid or the week before. Anyways so far so good. I’ll be showing more videos as the filter matures, any problems I’ve encountered, clean out, etc overtime. 👍
Great
Hey Kev, I have a question regarding the bog filters. I know you said for swimming they should amount to 25% of the pond volume. How big are yours and do you think it is worth it to use something like aquablocks to get the extra water volume? I heard that if a large percentage of water is not exposed to sunlight it can help deter algae blooms. Aquablocks are super expensive, so was considering ways to diy it (with milk crates and then plastic pallets on top)or ideally just use rocks as you have. Thanks for all the vids you're awesome, man!
I’m in the 25-30% range on this pond. I think the blocks probably help with sedimentation (holding more sediment inside the filter). I made a vid on alternatives. From a biological perspective I don’t think they are necessary, although the bigger the filter gets the more I’d seriously consider using them or alternatives, it will help with cleaning.
Awesome, thanks!
great job on your videos. I'm still confused about the bog and its orientation to the pond. Is the clean out for the bog next to the pond or away from it? It seems like it should be away from it but that would mean the water coming into the bog would be next to the pond which seems backwards.....
You’ve confused me. Might need to just watch a few more videos. There’s lots of different ways I’ve designed bogs. In this video the cleanout is a barrel inside the bog, the bog is seperate to the pond. A pump is placed inside the cleanout, only during a cleanout and the water can be pumped away from the pond onto the garden. There’s a recent video of one of these bogs getting cleaned.
I would like to use this system to filter water from a 50 m3 of water, just water collected from a small river, the idea is that the wetland (when is full of plants) remove any possible toxic compound the river water can be carry. Do you think it would work..?? thanks
I use bog filters to keep the water clean and clear. I’ve never tested it’s ability to remove toxic compounds.
That's not a pond it's an ocean. "Big green hardware store" 😂.
Mine's in trouble. I tried to just use a stream about 3m in length as my filter, it seemed to be working ok. There are swamp Oaks above my pond and they drop alot of needles. I try keep them out as best I can but it's gone kinda rancid and my rocks are turning black. Giving it a good clean out today. 🤞
😂 maybe not quite an ocean...but it’s pretty decent. Good luck with the clean out. 🤞
@@Ozponds It worked it's crystal clear again. Operation save fish a success. Thanks for your encouragement as always brother. 😊🌏♥️
Great to hear buddy 👍
Has anyone in the US been able to source an affordable version of the 'Evertrench'? The only solution I can come up with is ripping a culvert pipe - but they're very expensive. Thoughts/suggestions?
I’d love to know also so I can point people in the right direction.
have you looked at arc shield infiltrator sections they are 5'x3' about 39 dollars at menards.
Hello... I have a comment about the water jets. The way you have it is wrong. You need to leave a piece of pvc pipe after the last jet and cap it. Doing this the volume of water is divided equally into each of the jets. The way you have it, all or much of the volume of water will go thru the last jet and very little through the other jets in the line. Cheers!
Thanks Alberto good to know 👍 so far through it seems pretty even although I still can’t tell with the bottom jets (waters too cold). There’s a flow switch before the last jet so I can always dial it right back to force more water out the ones before it 👍
This is awesome, thank you, I’m now about to try this for my pond my old filter kept blocking up (multi chamber) and overflowed, the water washed out part of the bank and collapsed it slightly, how big is your pond I’m trying to get an idea of size I need to make the filter, again thanks this is great 👍
Pond is around 8 metres x 10 metres. 1.6metres deep. You should aim for a bog size at least 10% of the pond. Even more more if you want loads of fish. Hope that helps 👍
@@Ozponds spot on fella got to get the parts first struggling to get them in uk lol 😂
Can’t get hold of the half pipe in uk 😞
In hindsight, do you wish you had included the aqua-blocks? What, if any difference might that have made?
No I’m still very happy with these filters. Maybe if I were keeping a really heavy fish load they would be worthwhile.
@@Ozponds Interesting. Good to hear.
Hi I have a question. I am finishing up on my wetland filter. The size has changed to 6 x 12. I wanted to find out what you thought. I still have to put 3 different sizes of gravel in but when I am finished Should I fill it up with water right away? The reason I am asking this question the fish pond will not be finished for another 2 1/2 months so if I fill the wetland filter bog with water it will just be sitting there with no circulating water.
I can’t see any reason why you couldn’t fill it. I’m pretty much in the same boat. Mine is slowly filling with rain.
@@Ozponds Thank you. Hope all goes well.
I have plastic pallets. will it be ok to put them on the bottom of the bog with a clean out??
I’ve never done it, but others have told me they did and it worked great.
Noticed you could of went bigger by the over hang of leftover liner
One thing I’ve learnt is always have plenty of overhang. It’s so stressful if you don’t have play room. The overhang on these bog filters came in so handy when I butchered the seam and then decided to just go for an overlap. Because of the extra liner I was able to increase the height of the water in the bog. 💩 happens.👍
Which is the video where you go over the jets?
found it! czcams.com/video/mbpHe1q8cd0/video.html
I am trying to figure out the size of that barrel for the cleanout.
It’s a 220L barrel (44gal) I think it’s about 1.2m (4ft) high.
@@Ozponds Thanks!
Can you share details regarding the pump (that fills the bog filter). Should the pump have filter pad materials, bio balls, and a cage around it to pre filter the pond water prior to filling the bog barrel? Also, how do you keep a bog filter from freezing if you're in a more temperate zone? Just starting the planning now...
If you watch all the videos on this build it will show the entire configuration. It doesn’t freeze where I live so it’s not something I’ve ever thought about, sorry.
I wonder if old milk crates would work for the trench?
Quite possibly 👍
Great Stuff! I'm in the planning stage of building a bog filter and getting rid of the "pool filter", back flush every three days, and still having slightly cloudy water. I ran across your video with the half pipe and barrel. It seemed like this was an "experiment", and a great idea, to save alot of money, but I couldn't find any "results". Maybe I missed the results video. Was this as good as the aqua block covered intake bog filters? I'm still wondering why aqua blocks are used in the first place. Just a storage place for waste? Keep up the good work.
This has been running for a little over a year now. I’m very happy.
@@Ozponds I'm starting on mine as soon as it gets out of the mid nineties.
Hello, have you ever tried to cut a hole on the top of the barrel and let water come into the wetland that way? So you don't need a check valve or breather pipe? Also it's easier for the pump to release water into a big tube than go underwater in a 2" tube. What do you think? Thank you!
Well the idea of the barrel is that it’s for clean out, so by bringing the water in on the opposite side it helps just the heavy solids towards the barrel, while the lighter water disperses evenly throughout the bog and percolates up through the rock and pebbles. The pipe that the water discharges into under all the rock and pebble is much bigger than 2 inches. Hope that makes sense. But feel free to try whatever works best for you 👍
@@Ozponds thank you for the prompt answer. Yes I know about the centipede module, I was thinking only about the 1m+ pipe for going under the gravel into the centipede module. But I think I'll also stick to the normal way. Tomorrow I'll finish with the wetland filter digging. I'm thinking about drilling a simple hole on my flexi pipe as a breather valve on the highest level of the wetland filter and hide it with rocks.
@@Ozponds oh I totally forget that I won't use a centipede module at all. I'll dig a trench in the bottom of the wetland and simple put 6 heavy duty plastic pallets over it. In one end I'll install my cleanout pipe and in the other end the 2" flexi pipe goes under the plastic pallet.
What size linner was used for this video pond
Can’t remember off the top of my head. There’s a whole playlist dedicated to this pond. I know there’s a video on the cost break down it might be written down in the description of that vid 👍
Do you know a replacement for the halfpipe? I cant buy this in europe. Thanks in advance your the man!
Search for septic leech drains.
Does not exist or is a thing in my country. I will just have to continue looking for an alternative, thanks for the reply tho
Best of luck 🤞
What is the result from the test without matrix blocks?
So far no issues.
You need round pebble gravel
Round rocks will provide the best void spaces for water to pass through- Yes. 👍
Does the white piping run right through the half pipe, and into the olive barrel?
No
Hello Kevin great video I was wondering on how well that filtration work out without using pallet . I have limit space that would be ideal for me to do tyvm .
So far it’s going great 👍
@@Ozponds Great thankyou !!!
Almost finish with this design just wondering is that a 2 inch inlet pipe to feed your bog ?
Hi Kev.
I have my pond up and running now here in Denmark, geographically pretty much opposite you on the globe. I will make a "video" with stills and tell the story once it is all good - and my boy is back in school ;-) Thanks in large part to your excellent CZcams content, I paid just 2420 Aud for the whole thing! (Plus hours and gas for trips with stones.) The pond is between 2500 and 3000 liters, give or take.
Many things work well and I love my pond to bits. Water is clear (again, after the pump had to be replaced) fish seem happy and plants are starting to take off.
HOWEVER there is still one nasty bit of trouble I was hoping you might have a solution to: The water going into the bottom of the bog rises in large part up the sides of the hose that goes down into the bottom. So I suspect much filtration potential is lost there. Did you do something clever to avoid this problem?
Is the rock in the bog various sizes? Big on the bottom small on the top. It sounds like there is some kind of obstruction. In my bogs the seems to run evenly up throughout the bog. You can tell if you dig a little hole and disturb the sediment, it quickly clears due to the new water flowing throughout the bog.
@@Ozponds Yep, as per your brilliant instructions, I started large the first half meter, then medium (double walnut minimum). I wish I could send you a drawing. I have the tube go down along the rubber lining and into the... er... well, the bottom thingy (I used plastic half-pallets instead of your half tube). then geo-textile and rocks on top of that. I'm thinking I probably need to empty all the stones out of the bog (lord have mercy!) and move the tube so it, too, is surrounded by stones all the way down. Does that sound like something you might try?
(The bog is oversized and seems to work anyway. After a week of no circulation and algae build-up while I waited for the replacement pump, the water is crystal clear again after four days.)
You can send me an email kev@ozponds.com I do ask for a donation for personalised advice.
@@Ozponds Fair enough. I will try to put something together tonite. That way, I get to satisfy my desire to show you my little pond aswell. I've been wanting to do that :) Donate how?
I’ll send a link in the email 👍
In the UK I can't find any suitable half pipe, would it be possible to use a perforated fully round pipe? Similar size to the half pipe you use
Thanks
I can’t see why not.
Hey Ozponds, did you put a t junction on the top of the water inlet pipe? You mentioned this in another video as it lets air in and stops backflow in case the pump stops. Thanks in advance.
Yes both the bogs for this pond have the t piece that allows for the breather pipe. Came in very handy as we just recently lost power for over 24hrs.👍
Would you say the wetland filter works just fine without the false bottom or aqua blocks?
It definitely works just fine. The test will be when I give it a flush out this winter.
Hi kev, im going to incorporate my bog as a river/stream that flows back into the pond, how much water should i have ontop of the final layer of stones?
300mm or maybe only 100mm deep of water and plant in that?
Whatever you prefer. I don’t think it really matters. Just you’ll lose that volume of water when you do a clean or if the pumps shut off.
Thanks for the reply, is it important to have plants planted in the bog or can the bog operate well without plants?
Thanks
@@nuhomesrenovationslimited6976 bog can operate fine without plants.
Wow I have learned so much studying your videos thank you. I have a question please. I have approx 800/900 gallon pond and want to attempt the bog set up. I have some space to work with not a lot though. Apparently we need the bog to be 30 percent the pond so around 300 gallons or so. We have a lot of fish. Too many in my opinion. My thoughts are to have the intake into a barrel which will flow into an area with liner and rocks which will flow into a river bed. We are talking maybe 4/5 feet from bog with the liner to the pond. I am just not really sure the best method to do a bog which holds 300 gallons. This video buries the barrel which is the bog in conjunction to what flows through the rock bed to the barrel. Any suggestions on a smaller scale to accomplish the 240-300 gallons for the bog with liner. Also does the barrel count into the equation of 30 percent. Hope I did not make this question totally confusing.
Many thanks
Robin
G’day Robin. In this video the barrel is just a clean out port. The entire lined area that is filled with rock and pebble is the bog. The barrel allows a clean out pump to be dropped to the lowest part of the bog to completely empty it. When I want to clean it.. I empty the bog, I then direct clean water over the surface forcing all the muck to the bottom of the bog (remember there is a large drainage pipe connected to the barrel), all the muck finds it’s way to the barrel and is sucked up by the clean out pump. I keep pushing water over the surface till the water being pumped from the bog is clean. So in answer to your question this design is probably your best bet to create a 300 gallon bog. The hole that you will excavate just needs to be approx 300 gallon, then you will line it, create the void space, add a clean out port and layer the rock/pebbles over the top. I hope that makes sense.
@@Ozponds Thank you for your response. So the white PVC shown is the intake. I can't see the clean out port on the drum. Do you bury the clean out port using PVC then bring the pipe to the surface for clean out (with a valve). And then how/where does the water get back into the main body of water (pond). This is where I am confused using the liner. Seems it is backwards pushing the water from the pond, over the rocks, then where does it go. I am sorry I am a visual leaner and can't picture this. My pond needs help. We had a sort of bog in our waterfall, unintentionally made, which collected so much muck. Then we decided to get rid of our waterfall and re do it and now the water has large particles floating around and our bio filter is just catching up. I know the bog will work. Any additional information to help me understand those few tid bits is appreciated. Thanks so much!!

Great idea on a budget. Going to try this myself. By the way, what kind of pump did you use to move the water from the pond the bog filter?
I’m using these jeboa pumps czcams.com/video/AP4Zvy9w-ik/video.html
Is that 6" corrugated pipe?
Yeah but it’s not a full pipe. There’s a link in the description if you want to see what it looks like and the exact dimensions.
hi how did it go with out matrix boxs? do you recommend going with or without them? thanks
It’s only been running around 9 months. So far no issue.
Hello. I found the barrel, but the half pipe did not have an international shipping option . Do you have any other options that can be used as a centepede?
No sorry I’m not sure what’s available outside Australia.
@@Ozponds I was thinking about using some large PVC pipe and just drill holes in it.
That’ll work! Just make the holes quite large. Remember if you ever need to drain and clean the filter a lot of muck needs to be able to re-enter the pipe so you can pump it out.👍
@@Ozponds Will do. Thanks for the help.
Does the corrugated pipe have holes in it ? Can you explain a bit how the water flows and filters in this system?
Yes there are holes in the corrugated pipe. Water is pumped from the intake bays into the corrugated pipe. From here it percolates up through various layers of rock and gravel. These provide an abundance of surface area for the bacteria that clean the water. The water then returns to the pond via a small stream o’and waterfall. Hope that helps 👍
Thanks. So I guess what ends up in the "snorkel" is stuff that doesnt fit through the holes in the corrugated pipe? It is wise to make this sort of setup in combination with a stream channel and waterfall feature? So basically Im thinking corrugated pipe w/snorkel> rocky channel /artificial stream> waterfall all-in -one feature
The stuff all ends up in the snorkel and the corrugated pipe. Some will also enter the gravel. So the idea is you place a sump pump in the snorkel and clean out the entire filter. While you are pumping water out of the snorkel you are washing the gravel from the top. This no forces anything caught in the gravel down into the pipe, across to the snorkel and into the sump pump and out onto the garden. Hopefully that all makes sense. In terms of your design and what you are planing sounds good 👍
What size pond is that
The pond is 8m x 10m and 1.2m deep
Did it work well?
So far, so good 👍
Hey, do you know where to get cheap liner?
Unless you get it direct from China, cheapest epdm I’ve used was southlandliners.com.au
@@Ozponds thank you so much! By any chance do you also know where to get cheap underlayment / cheap alternatives?
Looks great. I've been looking at aquascape stuff and think how much!!! the aqua blocs are around £70 in the uk!!. I think it may be worth some for of blocks mainly to help with cleaning out.
My question is what pipe did you use for you centipede? I can't find anything similar in the uk, what is it's normal usage or did you cut underground pipe in half?
I believe I put a link in the description to the exact one I used. It’s purpose is subsoil drainage/ septic application. I also have a video that will help you save on aquablox.
@@Ozponds you did I missed it. Looks like it's a Oz thing, just did a search for Drainage Trench Liner and all the replies are Australian :). I'm sure if I keep searching I'll find something in the UK
@@garymorin4813 Did you find anything Gary? I'm having the same issue!
@@FlanMangler No, I'm still to build mine but intend to use twin wall drainage pipe, probable 200mm diameter and then 450 or 600mm diameter for the pump chamber
@@garymorin4813 Yeah, that was the closest I could find, but I only need about a metre and it seems to come in 6 metre lengths... I'm thinking about using a network of standard drain pipes but not certain if it will work...
Do we need false bottom for bog?
I’m testing it without. Just the pipe and gravel. It will work from a filter standpoint I just want to ensure it can still be cleaned out effectively.
That’s exactly what I was thinking too. I think you can still easily backwash it by inserting a pump in the control drum. I am trying to create one without false bottom. I am curious how effective your clean up would be. But nevertheless, nice job mate.! Looking forward for your next update 👏👍
Where do you buy the Geotextile underlay?
Cheers
G’day Jonathan. I buy mine from rock around the block here in Australia. It is also available through Amazon if that helps amzn.to/3iRC5kV
@@Ozponds thanks for the info. I live in the Adelaide Hills so will give the first option a look. Just dug a 25x20x2m deep dam/pond. Going to need quote a large filter. Also need to try and reduce the errosion risk as we can have a few hundred litres per second of water come through the property after a decent rain.
Sounds like quite the project. Good luck with it all 👍
What's the desired depth of a bog?
I don’t personally care about depth so much as volume. Some guides are adamant that the bog should only be 30cm deep. Aquascape wetland filters are covered in 60cm of rocks and gravel plus the aquablox. I’ve used an olive barrel on one of my ponds, that would be over 1m deep. All can work in my experience.
@@Ozponds you did your bog without the blocks and just the perforated pipe in the bottom with the larger rocks right on top then the smaller pebbles on top of that, how's that working for you? I had awe ha moment today after reading your blog... I'm not going to have fish and I don't need as much filtration or some complicated system as I had thought... kinda like anything e you get into researching and planning if you don't keep the simple foundation you can over design. I'm relieved now after remembering I'm not going to have fish lol thanks for your blog and videos.
So far I’m happy. I’m just doing an update video at the moment. In winter I’ll give it a flush out and that will be the test. But from a filtration standpoint it works fine 👍 Just remember even without fish nutrients (ammonia, nitrite and nitrate) will still be produced as leaf material, pollen and dust finds it way or is broken down within the pond.
any updates on this filter? cheers
Heaps. 👍
@@Ozponds curious about your wetland bog filter volume. is the volume based on how much water it can hold or total volume includes empty spaces plus volume of media?
I just calculate it when completely empty no media, rocks & gravel. So if pond is 1000 litres a10% bog or wetland would have a volume of 100 litres. 25% would be 250 litres. Hope that helps.
WHAT ARE THE DIMENSIONS OF YOUR WETLAND
This pond has 2. One is 3m x 2m the other is 2.5m x 2m.
Thx u
Hello
How tall is this barrei
I haven’t measured them but I would guess around 1.2metres or 3ft tall.
I have a piece of culvert pipe 16 inches in diameter and barrel about 2 ft im going to cut the pipe in half and try to duplinate your wetland
Sounds good 👍
