I can respect your level of experience. We are reaching out to the beginner with very little space in this HOW TO video series. Please stay tuned as we have some advanced construction videos planned for later this season. Thank you for your feedback!
What an awesome project!! You explained everything clearly and precisely. My pond dream is about to come TRUE! Thank you so much!!!
+Kweli Walker You are so very welcome! Thanks for watching!
Thank you from across the globe.
Passing passion and inspiring is why we are hear! Glad to spread ideas!
Following your way in my pond, it's a success since last 2 years.
What will he think of next? Eric you never cease to amaze me. Your inspiration is truly contagious.
Glad we have your attention. ;)
Thanks Wilson!!!
Thank you!
I always push the water out the bottom. It keeps the bottom of the filter more active and it also equalizes in the pipes before the water lifts up through the gravel. Additionally it buys you more time from the roots of the plants working their way into the pipes.
This method can certainly be used for aquaponics!!!!
Love all of your videos and This is a super interesting idea!! Whens the next video come out??
Another great video you rock.
THANK YOU for these tutorials omg
Thanks!
The only issue with this video is wherein Eric say's to place the manifold with the cuts on the manifold directed down - facing the liner. Don't do it - you'll regret it in that if you do so within a years time the water pressure blasting into the manifold from the skimmer will result in a leak in your pond liner. The pond digger series along with their products are imo the best out there. The Helix pump and the Helix skimmer have been operating flawlessly with virtually zero maintenance for just about two years now. Have not lost one koi due to the wonderful design of the fish safe skimmer. Anyway,...have a liner to replace,..along with constructing a newly designed manifold. What a pain! :)
Hey great job pondDigger , love your videos , keep up the good job brother , greetings from Newark , Delaware.
Rewatching this series. Where have you gone @theponddigger ?
Thanks CaZee!
Awesome no complaints here always good
Your videos are the greatest; really fascinating. Thanks for posting them and for making them of such high production quality. I wonder, since the slots are so evenly made across the manifold, if the water doesn't tend to come out of the near-end of the manifold in greater quantity than the far end. Have you ever, say, run a test with colored water to see how it really comes up out of the gravel when you hit the pump?
Thank you for the feedback. My producer is AMAZING! the flow in the system will change depending on the loading of the system. It's ever changing. We have done dye tests.
Hey there PondDigger :) I am about to start construction on a filter I'm building my wife, so I thank you for this series, it has been such an inspiration. I was wondering what your opinion would be regarding drilling holes in the manifold as opposed to the saw cuts?
One suggestion I would give, a lesson learned, is to make sure the slits cut are enough to effectively distribute the water with regards to the pump. I had a relatively low power pump, going to the bog filter, but the cuts I made to the pipes weren't big enough and all it did was put undue pressure on the pump as it tried to crank out its normal g/ph but the slits weren't big enough and the pressure built up. I would suggest testing to see if the water flow is about as desired by running the system before putting any rocks or plants in.
Good point. We recommend error on the side of too many holes or slits on a pressurized return side. I have seen small holes in PVC with high pressure pumps actually bore holes in concrete! Imagine what that does to liner!
This question reminds me - if I’m trying to find the right size pump for the pond, what extra considerations are there with the water pushing up through the bog? If any. It seems like it would take more pressure for water to be pumped up through the bog than just emptying into the top.
Hoping you can help, love your videos so informative. I'm worried the water to my bog plumbing isn't reaching the outer pipes. I have a huge bog, about 50'x6'x'1' pond is about 7500 gal. @ 18' round 3.5' deep. I have 2 pumps to bog (one at each end) they are each about 4500 gph. I worry my water is being directed to the pipes closest to where the pump hose connects to bog plumbing but not the outer pipes. Help! I'll try to attach a pic.. crap sorry no pic possible ugh..
Thank yoU!
I loved your videos on how to make a bog filter. Question if i may, why did you cut the slots on the bottom of the tubes?
Very well done 👍
ive been using water from my pond for years.always wanted to try aquaponics though
I'm building an upper and lower pond with a 12 foot height difference, and a 35-40 foot stream between the two. I've been looking at the PVC idea along with a few aquablocks (already purchased those) for a bog filter in the upper pond. For back washing I assume I would need some access with another pvc pipe to flush it out but I think I would just end up flushing stuff into each branch. I am trying to avoid the expense of a snorkel and centipede. Any advice would be great!
Freaking love the videos not too sure on the weird song for the intro! LOL
Great video and lots of good information but would it not be better to to put the end caps on without glue so the manifold can be cleaned if roots grow into it?I have a filter that is close to what you built but not as big that is not glued at all.
I like the smooth rock vs. lava rock point about the plants. But I also like the effectiveness of the lava rocks. Do you think a good alternative or compromise would be to put down a bottom layer of lava rocks then move to smooth for most of it? Or I guess another idea would be those manufactured plastic filter balls as a bottom layer? Or is it just not that important?
The roots become the massive spot for bacteria to colonize. I love lava rock but don't use it in my bog filters. It's good to see you contemplate alternative methods. I am not a fan of bio balls in pond filter applications.
I want to construct a waterfall on a 15'x30' pond. Would this be the same concept on a bigger scale, for example my 15'x30' pond? We have ducks and I need a vacuum system on the bottom of the pond to keep it clean. I also would love suggestions on the type of vacuum pump to use.
the pressure (and hence distributed exit volumes) would be more equal if the filter entrance was in the center. This could be achieved easily if the entrance was affixed like a ninth arm in the middle and then elbowed up the side of the bog.
could i fill the bog filter with sand with a layer of gravel at the bottom instead of gravel throughout?
Question...If I am going to build a pond that incorporates a large bog filter, waterfall and skimmer with internal water pump, can I use one water pump from the skimmer to divert the water to the waterfall and bog, or would I need 2 pumps?
I notice you have a plastic bin you are placing your piping with the holes facing down. what is your opinion for someone using a rubber liner. Should the slots be facing up or down?
Echoing the thanks of many others - but you just answered my prayer of what to do on my patio. Forgive me if already mentioned - Would it be good to keep caps off until after using skilsaw to get rid of any cutting debris from the inside of the pipe? Great tips tho - looking forward to the rest of the videos.
Thank you for the feedback. Keeping the shavings out is a good idea but not the end of the world if some remain. They actually make some filter media out of pvc shavings!
you just gave me an idea for a wicking bed
Not gunna lie. If I did half that much gluing up it would look like I was wearing blue gloves,not to mention buying my wife a new table. It's fun to watch someone with skill.
when you laid the piping in the bin you laid it with the slots down. shouldn't they be up? to force the water upwards?
Thanks for your quick respond! So is it okay for me to use the manifold that has slits cut on both sides (top and bottom) of the PVC? What problem will I have if I use this? Can you please also comment on the cleaning process of the bog?Thanks!
Lynn F. The distribution of water flow will be a little off in the beginning but it will balance out after the bog matures. Do use heavy, deep rooted aquatic plants like umbrella palms. Use aquatic plants like taro, pennywort, ruby runner, lotus and such. We need to shoot a bog maintenance video. It is in the plans but might be a while before we get to it.
Love your videos! I have watched your video a couple of time and I am inspired to build a pond with the bog filter. My husband help me made the manifold with the slit similar to yours; however i messed it up when i tried to help. Not knowing he had already made the slits and had them facing down , I went ahead and create the slit on the back side of the slits that were facing down 😕. So my question to you is: Is it okay for my manifold to have both slits on top and bottom of the pvc? My PVC is 1.5" for a bog that is 3'x3'. Can you tell me the purpose of the manifold? Can I just run the flexible pvc from the pump to the bottom of the bog and and let the water fill the bog? water naturally will fill the container it is in right?
Lynn F. The slits are in the pipe to help evenly distribute the water through out the entire bog.
The slots are so narrow, will they get clogged ?
Love your videos!
What's the reason for putting the filter slits facing down? Is it critical?
Thanks for your compliant! Yes it is critically important for the holes of the bog filter return to be in the down position. We don't want the gravel below the pvc to become non active. When we push water into the pvc manifold we want the water to flow out at the very bottom of the filter bed to give every section of the gravel to become ACTIVE. When using the 2" pvc it takes almost 2 to 3 inches of gravel to cover the top of the pipe. If we are using 12" of gravel and the outlet holes are on the top of the pipe, that levels 25% of our gravel non active. Hope that gets you on track. Best of luck to you on your project!
don't know if this is still an active comment log but I have a question? Why do you need the manifold at all incline the bog tank a few degrees and have incoming water enter at for end. Wouldn't it do the same thing as it fills to the overflow and into pond? Really like this concept by the way!
+David Kerrison The manifold will ensure equal distribution of water throughout the bog filter. Thanks for watching.
Would this application work on a larger scale?
Hello.
Can you confirm something for me which I've been getting to find out for about 1 week now? I have been doing research by watching video's like your's & looking at advice on the internet like groups on F.B. I have been informed that Pea SHINGLE should be used which IS different to Pea GRAVEL although they are listed as being the same in the shops, I understand that Pea SHINGLE is made out of Limestone where as the GRAVEL is made out of STONE! Does it matter which one I use?
Thanks from the UK.
Can the filter be made for 2 small ponds on each side?
Hi, nice work. Do you recommend wrapping the slotted PVC with a porous medium like underlayment or fine mesh screen to keep the fibrous roots from growing into the pvc slots?
+Kevin Williams I do not. The screen or underlayment will get clogged and the roots from the plants will tie up the screen or underlayment too.
+ThePondDigger Thank you - & fast reply!
+Kevin Williams Thank you very much for supporting our channel!!!!
I hope you still look back at 3 year old videos and answer questions. You stated you would go 12 inch center for bigger bogs. Would you put the caps at the ends of that kind too? Do you have any videos of building large active bog filters for big ponds? I am looking to build about a 4600 gallon koi pond with bog filter.
+David Guin By the way....I have watch almost 100 or so videos from you. You are an awesome teacher. You helped me build my first pond. I'd love to send you pictures of it.
+David Guin Yes i would still be installing caps on the end of longer runs in bog filters. I don't have any videos on larger bog filter installations but we can certainly provide some support with photos and diagrams if you email me direct.
eric@theponddigger.com
+David Guin Send me photos of your pond!!! I would love to see it!
eric@theponddigger.com
i dont understand with that bottom pipe function ?
where are your clean-out pipes?
excellent videos guys!
Thank you for watching!!!!!
We uploaded one yesterday and we film later today. Stay tuned!
I don't think you mention it in this series, but you should also be sure to test whatever rock you use to make sure it's not going to make your pH go nuts. Limestone and some other types of rocks will cause you to have a high pH which can negatively impact the absorption levels for your plants. Clay pebbles are best, and are lightweight (but expensive). You can test your rock by seeing if it's reactive in vinegar. If it bubbles, use something else!
Letters from a Psychopath That is solid advice. In our area the rock we have in abundance is an inert granite. I typically will suggest the homeowner check with their local rock yard to see the prevalent rock being used by local pond builders. Good Looking out Letters!
Why didn't you put the slits in it before you glued everything together
Your videos are amazing and have sparked a few ideas in my mind for both ponds and aquariums but i have run into a dilema. Would it be smart to use a settlment tank before your bog or would it hinder the plants? Also what size pipe should be used?
Ricardo Lomeli I would suggest a settlement tank before the pump and then send the water to the bog if possible. It will hold the plants back a little but not much! The diameter of the pipe will be decided on the flow rate of your pump.
What would you recommend for a 396 gph pump?
If you replaced that smooth stone with lave rock you would have 6 times the filtration at least. It cuts up roots? Never noticed..actually I never had any reason to check.
How do you size it for your pond?
that pipe deburing is like nails on a chalk board in that mic lol. great video though
+Jlaudiomustangs10 Never though of it that way. Thank you so much for watching.
Hi. Can I use a 4 inches pipe compare to a 2 inches as how you do it. So would a 4 inches pipe work?
Damian Yeo 4" pipe would require more flow rate... We use larger pipe on larger ponds with more flow.
Should wear safety glasses with circular saw )))
Love your project, though
My saw won't adjust, so can I use a angle grinder to score the PVC?
Eddie Baker I’m sure it would work just fine. Idea is to make them as even as possible
First, thank you for taking the time to put these videos together and post them. But PLEASE figure out how to fast forward the video past the repetitious steps. I don't need to watch you prime 15 pipes one by one, each side. Show me once at normal speed, then accelerate (not cut out) as if fast forwarding through the rest. Thanks
+DrDangerPuppy ABSOLUTELY! You're not the only one that told us. Palm to Forehead moment. Thanks for the comment and thanks for watching.
It's probably not too late to fix it if you're interested in doing so. There is likely software that will read the file, and then let you edit it - where "edit" involves a wide variety of things including fast forwarding. I was about to say the first thing I would check out is www.videolan.org/vlmc/ But I checked, and it is not stable at the moment. I've never used it, but I'm familiar with their VLC product which is a video player, not editor. Based on that, I would guess that the editor will be just as awesome. Until it stabilizes however, something else will have to do.
Just do it yourself it's so easy to skip forward a few minutes
Hi to watch your video's ..... but know i'm asking: were ae your safety massures to prevend to become hurt from all the dubree !!! A accident is in a small angle ...
Love the videos, but you really should be wearing eye protection.
YES!!! I agree. I was wearing eye protection in the other videos. Funny thing is production is always on me about wearing hats and shades so I had them off (accidentally) because we were filming. We are alway big on safety glasses! Thanks for putting my feet to the fire on safety!
@@ThePondDigger where have you disappeared to?!
Why did you stop making koi videos.
I know enough to be dangerous! ;)
If this was a DIY project, you would not use PVC primer. I mean let’s be real, it just isn’t necessary for something like this, that’s overkill.
if you want to know more contact me throu youtoob
With ALL that $$$ he has I'm surprised he doesn't have a cordless circular saw lol
This could have been shown in about 30 sec.
Once you glue one piece in place, we get the idea. You can move onto the next step. I really want to watch to the end, but my time is being wasted watching something I figured out after seeing it done twice.
I normally enjoy your videos, but these past two videos have been too elementary. The same step does not need to be shown three or four or more times
Lets start off the vid with a minute of incredibly annoying sounds. Great info though thanks!
