Happy Pondering ;) - Jak na to + styl
I love your videos. This one, and your lighting video, are two of the most helpful pond videos I have seen. Thank you so much for making them.
Thank you, just thank you. Clean simple and direct with a great analogy
We aim to please ;) Thanks for hanging with us ;)
So happy I found this channel, I just bought a home and planning a large koi pond, The information I just got probably saved me a Sh#% ton of work. Also your wetland video's are top notch. thank you.
Welcome to the family!
I learned a lot! I’m watching this again and taking notes. FANTASTIC!
Great to hear! Stay tuned for more educational contact coming this year :-)
The content you're putting out is great John. Thank you for your instructional vids!!
Always a pleasure, “Educate & Inspire” - thats my gig😎
Another great technical videos Mr. John G. Keep it coming! 👍👍
Educate & Inspire ;)
Love It.... Great Video!
Glad - hope it was helpful!
@@KoiAddiction Very!!
Thanks for sharing! Love the tip on the flow calculation site. Keep em comin!!!
I’m on it! There is so much more to teach!!!!!
Well dang! Thanks, Mister. That was very educational and I thank you for saving me a ton of $ and misery!!
Great video John. Way to break it down and keep it simple!
To be honest that really isn’t that much of a challenge for me😂🤣😂
Love this Video John! Thanks for sharing this Golden Nugget!
Hope to make a difference in the world, “Changing one pond at a time:)”
Pure Gold! Thanks for sharing.
Hope it helps ;)
John, I would love to see a follow up on how and why you select a pump based on a pond or pondless design. For instance is it just based on your water in motion calculations/TDH or a formula for cycling and filtering a pond as well. What factors determine solids handling vs non Fish, trees, amount of water in a pond etc...
Thanks for this great video. This is the kind of how to content I'm looking for. We want a pondless (or two?) and a pond, so we're going to tackle it ourselves. This is priceless.
Educate & Inspire-my mission👍🏻I am so glad it’s valuable to you, there is sooo much more yo share!
I appreciate your teaching! 😘
I hope it helps, we aim to educate and inspire ;)
Easy to understand, just what I was looking for...
Glad you got what you needed from it! Looking forward to making some more “pure education stuff” in the future ;) Jobs have been coming in and keeping us so busy it’s tough. We try to teach in all of our project videos as well!!
Very useful information. Thank you.
Thanks for hanging out with the Adams fam ;)
Great information my friend! Thank you!
No worries ;) Keep building em boss!
awesome videos man! I'm currently designing a my first backyard water feature and have been sponging up the wealth of knowledge and experience you've shared on your channel. Thanks!
My pleasure, hope its helping you!
That’s awesome to know, most people have no idea about this kind of stuff 🧐. Great video pops😎
Have a great 4th!
Great video!!!! Exactly what I was looking for! And a Calc to get it done.
Sweet, hope it helps you out :) Happy Easter!
Great tip. Thanks
Our pleasure, thanks for hanging out with us on the channel!
Thanks John 🍻 excellent again 👍
You’ve watched em all 😂🤣
Awesome information!!! Thank you Sir! Happy Fourth!!! 🇺🇸
And you as well! Hope you had a great one!
For those who want the maths, look up Poissuille's law. The rate of flow is proportional to the 4th power of the radius, meaning that doubling the radius (or diameter) will give 2^4=16 times the flow.
👀
This is a great video
Thanks MJ! You been sneaking around in our channel…
@@KoiAddiction all the time ha ha
Good stuff with even I understand.👍🏻🇺🇸
Thanks for watching and sharing :D
Great video! I’ve been referring back to your videos for help! So thankful for your experience and expertise! I actually used this video to determine the pump for a current project. The wholeTeam is doing awesome! Hope to meet sometime
That is so awesome to hear :-) glad it’s helping will continue to share and definitely meet you soon🤙
Excellent info. Thanks.
Did you learn anything??
@@KoiAddiction Yup. It's goofy, but I NEVER thought about increasing flow by using bigger pipe ...only bigger pumps.
So it was worth the time! If it helps 1 person, I feel validated😎Thanks and happy 4th👍
hi.. im from indonesia, thanks so much for the shared knowledge!
That’s so,cool, tech is the best! Thanks for hanging out with us. Doing a new educational series on “Ecosystem Ponds”. Let me know what you think!
Thank you. Nobody on you tube is talking about this stuff. I need a wider pipe !
😂🤣It’s the little things we learn over a lifetime😎
nice work!
Thanks for hanging with us!
Great videos thank you. I do have question.
If there is a wetland (8x10ft) with that is below the level of the pump but there is a water column on top how do you calculate the head pressure?
(I currently have a 3-PL on it but would like to change it.
Thanks
Hope it helps you out!!
I love your content, very informative. What clean out pumps would you recommend for your annual clean outs?
We use the blue cleanout pumps from Aquascapes. We have tried other types but those seem to work best all around and ho,ld up well to the abuse!
I love your videos! In the process of watching them all. And seeing what I can learn. Do you do training classes or know where to sign up for some are? I am a contractor in Indiana
I just do,educational videos currently. Aquascapes has the academy if you want more!
Great video!!. How do these concepts work in the case of a swimming pool?
Same principals- more fittings (don’t forget to add head pressure for those).
Do you submersible pumps on rec ponds folks will swim in? Love the videos you do. Very very educational!
Yes external pumps for recreational swim ponds are a must in my opinion. That’s what we are using on the pond I am currently building at home.
Hi John, Thank you for the valuable explanation. Can one replace the PVC pipes for flexible pipe, eliminating the 90% bends ?
Yeppers
Great informative video John, and the info about the larger pipe diameter invaluable - thanks.
I have a question too: If my pump is in the bottom of the negative edge reservoir and is pumping water up (say 4') and then across at ground level (say 17') and then down into my centipede module (say 3') how do I calculate the differential elevation? Matt
I go from “operating level” in the reservoirup to highest elevation level for lift height. Then use all piping involved for your run and typically add 10 feet of pipe for every hard 90 that I use.
Great video, quick question. If you go to a 3” pipe to get better flow rate does it matter that it has to be reduced for the pump fitting and biofalls ?
The reduction will increase friction loss so the shorter the better on the length of the smaller pipes and be sure not to exceed the flow rates on your biological filters- it causes issues!
The kids are out building stuff and youre stuck behind the camera, learnin' folks. You done got bamboozled! 🤣
True story, I got a let them have a little fun though🤠
Helo Jonh G. thanks for all your videos, they really help. In one of them you mention not to use a submersible pump in a recreation pond. Ist´s just for safety or is any other reason. Thanks from Puerto Escondido, México
It is a safety thing. No other reason. Hiding externals is more work BUT in my experience most of them are affordable and repairable in comparison to some submersible pumps so there are some other benefits.
Hi John what size pump should I use for my wetland filter. The wetland filter is 7' x 12' the pond is 10,300 gallons I have pumps running the waterfall already and skimmer. The wetland filter will be done this spring. The feed into the wetland filter will be coming from the intake bay which is about 20 feet away. Elevation which is the head will be about 2 feet at wetland filter. Which pump do you recommend for this wetland filter GPH and what size hose. If I have to use two pumps one for the intake bay and one for just the wetland filter I could do that also. Thanks
I would love to see the wetland design. Typical flow in our designs is 1500 - 2000 gallons per centipede assuming you have followed similar design practices. Be sure you use actual flow rate on your pump using the pump curve and flow losses based on total dynamic head.
Great video, thanks. Do you have a minimum of how many times per day you like the full pond volume to be circulated, or is it mostly waterfall appearance you go by?
1-2 times per hour turn-over for small ponds is my goal. The bigger the pond-the less it turns over though!
@@KoiAddiction This total turn-over volume of water would go partly to the wetland (volume per hour calculated based on its size) and partly to the jets, right ? (thinking of a swim pond)
Thank you for this explanation, it clears up a lot for me. Keep up the great art that you create and make us understand more about the how and why.
I am trying! It’s a challenge but the comments from our viewers inspire me to keep teaching :)
@@KoiAddiction 😱 WOW! that is AWESOME now
what's the $ CHA-CHIG COST for a pump like that?
Hi, big fan here. I have watched this several times to make sure I am understanding and at last I am in a position to be able to use this info to help me get the right pump so thanks. One question though, if the pump only has a 2" outlet will you still get the 60% increase in output by increasing the pipe to 3"?
Yes, though 60% was the difference in my example-you will have to run the total dynamic head pump curve with your pump to see what the difference is in your case!
Awesome video. Subscribed. How do you not have more subscribers?
We 🙏 for hanging! Stay tuned well keep it coming👍🏻🤠
Hi John, How do I work out which pump I should use for the GPM? Do I just keep a record of all the different GPMs and then try them in the TDH calculator? Sorry for these questions as I’m very new to this my total length is 7 m, and the photo is about 2 m?
Thanks Damian
Yessir, keep plugging in pump stats until you find the right flow and a pump that is operating in its “happy place” IE the feet of head pressure is in the sweet spot for that pump!
John - Great info. Your examples are both submersible pumps. I will be using external pumps. If my external pump has a 2” port in & out do I get the same boost by using 3” flex both on my extraction from the neg edge reservoir and out to my wetland filter? Or should I draw water out with 2” and push to my wetland filter with 3”. Help please! :) Do I just “neck up
My fittings at the pump housing?
You need to run the pump curves using the formulas to be sure you are still in the pumps sweet zone. As long as you are not exceeding the pumps capacity on the draw end (length, head, etc.), you will get more flow with bigger plumbing. Just make sure it doesnt decrease head pressure too low for the pump! Did that answer the question?
Yes and thank you! I will pay close attention to the calculations and TDH.
Hey John a pond with an intake bay with an aqua scape pond vault what’s the best way to run a overflow drain thanks
Pit a 12” drain basin next to liner for over-flow or use a simple dry stream style overflow next to the intake at a low area🤘🏻😎both is even better!
Great video, you've really made it simple for people thinking about ponds! Speaking of lowering friction and hence pump head, why do people use such long stretches of flex pipes when this is really terrible for friction losses? A straight pipe will get you 10x less friction. A flex pipe will never achieve laminar flow, and turbulence and all the slight curves will add to friction losses. What are your thoughts on this?
For most applications it is about ease of installation. I have used both types but typically it is just easier. So much time saved in construction doesn’t make financial sense to hard-pipe smaller jobs. Lots of elbows can off-set the friction loss on flex-pipe. Most of the time the mistake I see is too small of diameter on pipe eating up flow rate. I will use a combination of flex and sch. 40 on my feature, depending on the run and how crazy it gets.
Hi , I have a swimming pond in NY and I don't like the idea of having the pump in the water for posable electrical shock and we freeze up here so I would be removing the pump every winter. Is there a dry transfer style pump you would recommend for 18' lift 1500 gph?
Call the guys at Performance pro, You will have to give them specific information but they were spec you the right pump for the job.
Does GPH change if you split a 3'' pipe into two 1.5'' pipes? If so....based on friction loss, I would assume that you wouldn't want to split it any closer to the pump than say 5x the diameter of the pipe.........but I could be completely wrong. Any thoughts?
Yea,I keep the main line at a large diameter as long as possible and try not to put more jets than the flow permits- so if I have a 10k flow I will use a max of 10 jets. If you are concerned use larger jets and then you can reduce down again if you need more push. I’m no engineer- I work with pump company and a diagram on larger systems!
Dude where were you all along, thanks man
I’ve just been out here making videos and building water features. Glad you found us ;)
Thanks for sharing! What an informative video !!!
Would love to get your input and recommendation on my pump. My pong is about 15' long, 8' wide and about 3' deep about 2700gal pond. What size pump you recommend...the aquascape 5000, 3000 or 2000 pumps? Please let me know. Thank you so much.
I love the Aquasurge pumps for efficiency BUT they need to be properly installed in a skimmer in a low head scenario. Be sure to use the total dynamic head calculator to determine actual flow with each pump you are considering to find the perfect choice!
@@KoiAddiction thank you for responding! Information noted !
Hey jhon thanks for your information got a 3 inch line running into the pond for my three jets would I come off the 3 inch line or T off into a 1 inch or 2 inch line for my jets thanks again
I do 3” in to carry high flow-when split do 2” lines from tee “splitting” the flow, then reduce to 1” only @ the jets for a short run. You get more flow that way!
Hey John quick question using an adjustable Flow SLD 4 to 7 GPH running the 3 inch line how many jets could I possibly put in and still have a good flow Ponds kind of large and about 5 1/2 foot deep thanks again
Hi guys. Another question for ya. I am wanting to move a lot of water (315 gallons p/min). The TDH is 3 meters. (4 inch pipe, open-ended system - so from a lower pond up to a waterfall). I have seem some installers will put multiple submersibles in parallel. So in this case, I could use 8 submersible pond pumps (all high flow, low head), or I could use one high power external pool pump to do the job. The disadvantage of the external pump is noise really. I am concerned about putting 8 pumps into on 4 inch pipe though. Any thoughts on this?
I would do the external probably and figure a solution for the noise. Final decisions would be based on Pond purpose, pump cost, electrical costs, etc. Weigh the pros and cons. I have never pushed multiple pumps through the same pipe….that’s interesting. Seems like it might create a competition…I would love to hear more about that and why it is a good idea or not.
What flow rate do you recommend for a Jet? ie If you are using a low -power high flow pump to run 8 jets (so there is no head other than the pipes) what is your minimum flow rate per jet?
500 gallons min 1000 gallons max on a 1” jet. Max 1500 GPH on a 1 1/2” jet
John loving your videos there very inspiring building a small stream and waterfall 11ft long 2ft wide average 1.5 deep average the height of the Waterfall 2ft and 15 inches wide at the top,will the Aquascape Eco Wave 2000 which has a maximum water pressure of 7647 Lph is this suitable for my project. 🤔
Youll have to plug your numbers into a Total Dynamic Head Calculator (google one) and then match the head pressure to the pump curve (in catalog & on box) to see what your actual flow will be after head pressure and then decide if its heavy enough for you. Ill shoot a video on this next week!
@@KoiAddiction Thanks! John really appreciate it, nothing bought yet still in planning only part of my tropical paradise. 😂
Hey I have a question. I’m going constructing a pond and I’m putting in a wetland filter as well as a spillway that’s on a different side of the pond then where the wetland is. Is it ok to “T” into the pipe from my vault or do I need two different pumps? If I can T into the pipe can I just buy a ball Valve on the pipe to the spillway to regulate the water? Just wondering if there is going to be enough water volume for both
As long asyou dont starve the wetland-plan for the proper flow and size the pump accordingly!
Thanks for the advise. Your videos are really helpful
Hey John one question on this topic if I go with a 3 inch flex PVC but there’s only a 2 inch coming out of the pump once I use the 2 inch into 3 inch adapter will I still gain the extra flow rate or will the 2 inch section cancel it out thanks for your info
No you will def gain the advantage. Keep the 2” as short as possible👍
The reason being that a 3 inch works better than a 2 inch pipe is the friction of the water against the inside of the pipe. The bigger the pipe the less water touching the pipe that is why you can start with a 2 inch pipe then increase to 3 inch pipe and get more flow out of your lift.
Yes, what Mark says! 2 things affecting your flow inside the pipe are velocity and friction loss. Think of people walking in a hallway- the skinnier the hallway the more difficult it is to pass. As you add more people (higher flow) the passage becomes more difficult. As the hallway gets bigger (larger pipe) the passage becomes easier 😎
👏🏻
Hope you had a great 4th!
I have a 22,000 gallon pond and am planning a waterfull height of 2-3 feet. What size pump would you recommend? My pond is 40 L x 30 W and averages 3 ft deep.
There is so much more that goes into the planning of the proper pump. I would have to know lift run size of pipe requirements of your filter, type of intake, etc. in order to be able to properly. Answer your question. Typically I try to use multiple pumps because pump redundancy is a safety net, in case one burns out which always happens eventually. I’d be happy to talk with you about it, but I would definitely need more information :-)
Just been thinking. How is the the bigger bore pipe principle effected if the outlet of the pump is 2” then the 3” pipe going into a 2” bulk head of the bio falls. Thank in advance. Your videos are superb 🍻 please keep them coming 👍
The higher resistance only applies to the length of run in the small pope. Keep it short to maximize flow🤘🏻
@@KoiAddiction thank you that makes sense 🍻
Can you combine a wetland filter with a pond iongen? How? Ion gen installed between pump and wetland? I hope this gets an answer
I would put the ion-gen on the blow-off valve from the wetland. Don’t try to put it on the pressure side!
Modern Design Aquascaping Inc. Okay thanks! But what is the blow-off valve?
Hello... the pump is how many liters per hour used in the waterfall
I do GPH. Flow should be 1500-3000 GPH per foot of waterfall width (as a rule). You can always do more BUT that is a rule of thumb!
OK so I built a pretty decent sized pond on my property and did my first waterfall (inspired by dad and his CA backyard goldfish pond, RIP dad). My pound is roughly 300 long varied withs from 20 wide to 85 wide variety of depths 5 deep to 14 I wanted to be natural looking and a roundish island about 25 feet round with mature cedar trees. Now my big waterfall is in beginning stages I have a upper pond 12 15 feet round 3 to 5 deep spill over a fall of 18 feet to splash hole length from main to upper total 26 feet tall and about 130 feet long. 3 inche pipe how do I figure pump size for min 6 feet wide by 2 inch curtain or am I dreaming to big
I think 6’ wide x 3/4” thick is about 15,000 GPH. SO that would be ABOUT 40,000 GPH flow to get about 2” thick @ 6’ wide. That won’t go through a 3” pipe. At low-velocity you are going to be pushing 10.000 GPH ish in a 3” pipe.
@@KoiAddiction so 2 inch deep is probably a bit overkill would 3/4 inch depth be to small or am I running multiple pumps. I can adjust as this is my personal project
Thanks
My pleasure!
