The BEST DIY POND FILTER for CRYSTAL CLEAR WATER

[@TheDrillMaster001]

OK. Sold. Your guidance is so good. I've mentioned before that I have a large natural pond on our acre of land that is now going through algae buildup on a large scale. We have leaves constantly decomposing in the water and nitrogen is doing what it does. I'm going to build a bog filter, but it's going to have to be pretty large. A great undertaking for this summer!

Video is not too long. Currently building my own DIY pond with bog filter in my garden all with thanks to you for both the knowledge and inspiration. Even tho I have watched all your videos and already know all this information, each video gets better than the last and its great to have it all reinforced. A valuable watch. Cheers mate, from Ireland.

[@Ozponds]

I do feel like I repeat myself a lot, but it also seems to be the information people need to constantly hear, based on the emails I get. Once it’s like “I’ve heard this a hundred times”- that’s when you’ve got it all sorted 👍

[@claireoliphant7775]

I used your videos as a core part of my design process for my backyard pond and they were wonderful! In my design I have a pipe inlet at the bottom of my bog filter, and a cleanout pipe next to it. Both can be closed so I can avoid backflow if needed. My pond overflows into a short creek which serves as a secondary bog filter, and I have a 100 gallon water storage/pump pit at the end of that, so if the pump ever stops unexpectedly the backflow ends up there rather than the pond. In the nearly 3 years I've had the pond I haven't had to do a cleanout of the filter. Oversizing the filter set up and using your methods has given me a pond with very low maintenance, and a wealth of wildlife watching opportunities. Even though my pond is built and established, I still enjoy watching the videos. Thank you so much for sharing all the info!

[@Ozponds]

I’m so glad you were able to use some of the design elements I talk about and you still enjoy listening to me ramble on. Thanks for the support 😊👍

[@MandyJane123700]

When I was gathering the supplies to put together my container pond last year, I watched several different pond channels. I had a collection of them, but none of them really seemed like something I could manage, until I found your channel (and the bog in a barrel video).

[@Ozponds]

I also felt like that when I started learning. But as we both, now know it’s not that hard and the rewards are tremendous.

[@frankcanale3467]

The pump was a little strong so I added a T and valve to adjust the flow thru the bog. I have it running in test mode to make sure there are no leaks. I am happy with the setup and plan to add the rock layers next weekend when I return for my weekly visit to check on my Mom. I will keep you posted on the progress. Thank you for your videos, they have been a great help. Frank

Thank you for this detailed video on your unique approach to designing and building bog filters. I'm trying to convert my current down-flow "bio filter" (using plastic parts and foam filters) to an up-flow bog filter with rocks and pebbles. My current so-called bio-filter isn't working very well. Sometimes, the water cleared but most of the year, it is greenish with single-cell algae. Your advice on size, flow and ease of maintenance will help me in designing and implementing this conversion. Kudos. Subscribed. Thanks.

Thank you - a big fan. Your ponds are beautiful. It has taken 8 months but I have crystal clear water. I'm not the brightest bulb on the tree when it comes to science and math, so it takes me a little longer to accomplish. I built a bog that may be too small ?? Put plants in it. Not even sure about the water pressure and the outflow gallons per minute but I watched, many times, the flow of your water from the beautiful orange pitcher in the little pond and duplicated that.Added river rock and some other items to help with beneficial bacteria. Finally after about six months or more the water started to clear. Actually did some water change. Added Nualgi . Still not clear. Then pvc pipe with holes drilled for water flow around the inside perimeter of my 4' x 7' x 21" diy pond. Using an extra pump. In no time at all the water quickly became clear.. I am thrilled. After almost three years of trying, you helped me have clear pond water in about 8 months. I couldn't be happier, Now I realize that water movement does make a big difference. THANK YOU

Finally got my Uniseals this week! Now it's a matter of building the bog filter (a plastic plant pot that's outdoor-proof) and setting it up. I'm using a solar pump, because it's a little 9 gallon 'pond' hard liner. Sadly, we don't have outdoor electrical outlets, so solar it is. My little non-filtered sink pond is doing great, as I have had the little solar pump up off of the base of the sink (there's pond liner in it). There's the biological matter on the bottom, but the water itself is clear. :) Thank you for your guidance and suggestions in your videos.

[@robertcowie7393]

I have struggled to maintain a clear pond for several years and have tried several solutions. I finally built a bog pond using two 300-gallon Rubbermaid stock water tanks.

Your videos are great. Things are actually so simple and not expensive at all. So many places want to sell you expensive filters . Loads of chemicals and so on. When all you really need is to imitate Mother Nature. Quite simple actually. I wish I’d have had all your information before I built my pond. I went through months and months of frustration until I got my eco system working correctly. I now have crystal clear water. Only small amounts of algae ( which the Koi nibble on ) and plants that grow fantastic. Inpatients in a bog grow beautifully! I have Lilly’s and cannas which are beautiful . Only maintenance is cleaning the muck out of the Jap mat on by bio fall waterfall. I have good sized Koi so there is a load of waste. I don’t use any chemicals, just add more bacteria time to time. You’re spot on and I love your channel 👍🏼👍🏼

Hi Kev. Thanks for keeping the content and inspiration, flowing. And making the info crystal clear. ❤ I have a 500 gal pond with 3 koi and a few mosquito fish. I made a bog filter from a whiskey barrel. I've had it running for about a year. I cleaned it out a few weeks ago and was amazed at how much muck it trapped. But I still have green water. I bought two more 55 gal drums. Would you set them up to flow consecutivey (filter A drains into filter B) or have separate pumps for each filter? I put lava rock in laundry bags (in my filters) sitting on top of a milk crate. When i tried to clean it i washed it out for a considerable time, but i still had lots of muck in the barrel. So now I've changed it. Sending you love and gratitude!

[@Ozponds]

I feel like you could do it both ways. Basically as long as we have enough surface area for the bacteria, easy clean-out and the flow rate in the right ball park, you should get your water clear 👍

Aquaponic grow beds are the same as a bog filter, pretty much 👍

[@sandyl1899]

Bog filter here we come!! Thanks Kev. 😊

[@insAneTunA]

I pump half of my pond water into 4 separate bins made from IBC containers that I have cut in half, those are filled with lava rocks and each bin has a siphon. When the water in each bin reaches a certain level the siphon drains the entire bin and the water goes back into the pond via a sump tank. The other half of the pond water goes through a vortex filter and a regular pond filter that is also filled with lava rocks directly back to the pond. I do not use UV lights. In each bin, called a growbed, I grow a variety of plants such as strawberries, chive, monk's cress, some flowers, reddish, and even a laurel tree. This system is called aquaponics. My system is a figure 8 setup, which means that one loop goes to the growbeds with the rocks, and one loop goes to the pond via a regular filter, but both loops share a single sump tank that is made of a single IBC tank that is buried into the ground. That is where the pump is situated. I keep it running all year long, even during the winter. I keep making improvements and recently I uploaded a video with an update from the system. It basically is a bog filter, the only difference is that the flood and drain system, that is how a system with a siphon like I have is called, helps to provide oxygen to the micro organisms and the roots from the plants, and therefore you can plant a wider variety of plants. It is a bit more complicated to set it up, but once the hard work is done it is easy to maintain, and to grow vegetables and fruits which you can eat.

[@Ozponds]

Exactly right a bog filter is basically the same as a aquaponic grow bed. Your setup sounds great 👍

[@insAneTunA]

@@Ozponds I think that you are doing a great job with your videos. So once in a while I go to this fish pond supplies store, and then I see these highly sophisticated mechanical filtration systems with rotating self cleaning drums and all sort of mechanical filters and energy wasting and microbial killing UV lights that costs thousands of Euro's, and I never get it why people even buy those things. My entire system is driven by a single variable pump, and at the pumping rate that I have set it the energy consumption is 55 watt maximum. And that is all the energy that my system is using. And like you said, crystal clear water. Sometimes I have some algae during the transition of seasons, but I am working on some modifications in order to keep temperature fluctuations within limits.

Good day Kev! Ive watched a lot of your videos on bog filters and literally began building one that is about 4 and a half feet deep, when I came across your video talking about how deep it should be at max. Do you recommend I try and make it shorter? (Bog itself is being made in an above ground 7 foot x 12 foot container. About 2500 gallon bog for my 6000 gallon pond) My only other question : when it comes to making a void / false bottom is something like corrugated drainage pipe snaked on the bottom sufficent (or even necessary? haha) Thank you so much for all your knowledge and expertise! I appreciate you so very very much.

[@Ozponds]

That depth seems fine to me. I’d prefer the void be something a bit more substantial if you expect a lot of waste to accumulate in the filter (large fish, turtles or ducks, ect).

[@oots4790]

@Ozponds Thank you for the reply! I appreciate the suggestion for something more substantial. To aquablock my large bog it'd be quite expensive but that is what I started off thinking about. While I don't expect an enormous amount of waste, (mostly fish and frogs in my pond) I would love to future proof it for something like turtles and ducks. You've answered and helped enough, if you're willing to reply once more what's a good aquablock substitute (if there even is one) I was thinking reinforced milk crates of some sort potentially. Unfortunately those aquablocks just can't feasibly be in the budget for me at this time. Genuinely wish you all the best!

[@Ozponds]

That’s pretty much what I do. I just use a homemade skimmer or intake bay to provide a pre filter to the pump. If the pond is under 1000L I’ll just plop the pump in a plant pot and use a course sponge to protect it from getting clogged.

[@inganeerable]

I just finished building my bog filter after watching your videos. Thanks for the info. Do you have any feedback on how to keep the pond oxygenated adequately? Do I have to have the big outflow fall into the pond or can I pipe it down with no waterfall?

[@Ozponds]

Every ponds oxygen requirements are different. I know I’ve made a few on aeration/ oxygen. The general rule with the water leaving the bog is to have it cascade or splash back into the pond, the reason being that as the water moves through the bog, the oxygen content is being consumed by bacteria. Therefore we want to reintroduce oxygen. Hope that helps.

[@julian.morgan]

Thanks for another great video -please could you comment on the plausibility of solar powered pumps or even make a video about them? I'm talking about pumps that would really only run effectively in direct sunshine and so not run most of the night. They may have a small storage battery that would run the pump for a short period after dark, but are unlikely to keep water flowing through the whole night. Traditional theory is that these won't work because nitrifying bacteria are oxygen dependent. Stop the water flow, you stop the oxygen, the bacteria die and your filter crashes. However, I have also read fish-keeping forum threads where people are asking what to do in the event of a power outage stopping their aquarium pumps/filters from running? It would seem that more recent research suggests that while bacteria/archaea can obviously only oxygenate ammonia and nitrites in the presence of oxygen, the absence of oxygen doesn't mean that they die - at least not quickly - but instead enter a non-active or dormant state, at least with regards to nitrification. They die quite quickly if allowed to dry out, but their die off rate is actually quite slow merely from lack of oxygen. Some suggest that only after 24 hours of lack of oxygen do you begin to get serious rates of die off. This of course is really intriguing for solar powered pond pumps for our filters, given that most of us don't have more than 16 hours of lack of light even in the depths of winter. Wondered if you have any real life experiences to share?

[@Wakeupandsniffthecoffee]

I made a bio filter with a 55 gallon plastic drum, basically like your diagram. I had it running yesterday and went out to let the ducks out and disaster had struck overnight. Apparently my first mistake was bullying it on the hardened clay I dug from the pond, but gave it about 3 feet high above the pond. Some time during the night it must have plugged the outlet and flowed over the top. This in turn eroded the clay underneath the drum and the weight toppled it over. The pump continued to drain the entire pond at that point. While the bio filter is a great idea, attention to details like a firm foundation and perhaps a secondary overflow hole would have saved it.

[@Ozponds]

Unfortunately I can’t foresee every possible scenario. But this is why I always stress the overflow needs to be oversized. Hope you get it all fixed up.

[@StaceyRoberts-s3b]

I’m a newbie, I ran across your videos and I absolutely love them. I had a professional install my small fish pond with concrete around it. The pond is only 125 to 150 gallons. I am not able to keep the frogs and crayfish out I guess because we have a natural pond about 50 yards away. The small pond gets full sun until 3 PM. The water gets so green after 4 to 6 weeks I have to completely drain it and start all over. I went to my local “pet store” and that’s what they suggested at first. Then they said that I would never be able to have clear water because of the factors against it. Would you agree them? Or do you think it would be worth my time to do one of your homemade bogs?

[@Ozponds]

I’m biased. The bog will work!

I’m making my bogfilter. But a thing that anoys me is that the breatherpipe makes a loud slurp sound. Whats the best way to to get rid of that? Put the breatherpipe just under the waterlevel? Or should i add a nonreturnvalve?

[@Ozponds]

Under water would work, but first just try sticking a sponge in there.

[@MooseCannon]

Can you have the pump only run during the day if the filter is large enough? E.g. solar only powered pump?

[@Ozponds]

I have a solar only setup. You can check it out if you like. It was about a year ago.

[@Jesusisnumberone5740]

Look into using charcoal as part of the filter. Has tons of surface area

[@kathrinepet7623]

Can you use 2 bog filters one flow in the other before going to the pond ? Thanks for all the information you provide us in the videos.

[@Ozponds]

It’s something I get asked a bit, however it’s not something I’ve personally tried. I think it would work just fine.

[@knotknots6601]

​@Ozponds @geschichtentraeume I have a std. pond filter with UV followed by 4 small slightly varying design bogfilters(?) at different levels on one side of a mound with small waterfalls in between all filters (downflow where water falls into the filter, goes under a barrier and flows up to next waterfall through varying material and vegetation on top). 1 pump, the rest is gravity. I would think it actually could be beneficiary, as you get multiple aerobic - anaerobic cycles?🤷‍♂ Actually, I always thought the first step of treatment should be aerobic (like at a waste water treatment plant), to start nitrification NH4+ → NO2- → NO3- . So, I have a question regarding choice of pumping water from the bottom of the pond directly to the same conditions at the bottom of the bogfilter without aerating it first. Is the waterflow creating negative presure and actually sucking in air via the breather pipe or is there an advantage to keeping a more anaerobic condition, but with vast increase in surface area?

[@sanfordlopez]

Thanks for your videos. I made a bog filter. The bog is a 70 gallon tub and my pond is about 1700 gallons. When I first set up the bog, the water went crystal clear after about 4 days and it stayed really clear for about 2 months. Then it gradually went back to allowing the fine particles to pass through, making the water very murky as it was before I installed the bog. No matter how much I clean the bog, it will not clear the water as it did when I first installed it. Is this because the bog is too small?

[@Ozponds]

Maybe, the bog is small. It also depends on what’s creating the fine particles.

[@sanfordlopez]

@Ozponds the fines are from not having gravity fed bottom drain. I have a retro bottom, pump fed and the pump grinds up everything to tiny fines.

[@Ozponds]

@@sanfordlopez sounds like you need some kind of mechanical filter.

[@kevinwhite1077]

nice video keep them coming

[@elizabethdg]

I have a very high maintenance 5000 gal pond with two aquascape waterfalls connected to one skimner pump and a moving bed waterfall connected to a bottom drain. While the water is clear I still have a tremendous amount of muck on the rocks along the side and bottom. Every two or three days i have to hose down the filter mats positioned along the waterfalls. Its dirty, time consuming work. Is there any way I can add a bog without lisng my waterfalls? Thx!

[@Ozponds]

The simple answer is yes. Just run a separate, dedicated pump to the bog filter. It won’t clean your rocks though.

[@danielbello8947]

Do the type of rocks matter? I purchased a house with a pond and it’s had red lava rocks in the big filter. Water is looking green I’m wondering if changing these or adding more rocks will help

[@Ozponds]

Shouldn’t make much difference. Just sounds like there’s not enough.

[@leohorishny9561]

I am having a new issue with my bog filter I can’t figure out: the pump drains my water feature, but fills up the bog filter with that water despite the overflow pipe draining water. It ran fine for a couple days, after restarting the filter for spring, but today it's started this pattern. I’m stumped.🤔

[@Ozponds]

I hope you get it figured out 🤞

[@davidcox5250]

Should I add pebble to the bottom of my metal stock tank pond?

[@Ozponds]

It can provide more surface area for bacteria. But if you have plenty of filtration (like a bog filter) it’s not necessary. Depends on the look you are going for.

[@3_3645]

Do you have a video of how you filter water for an aquarium? I tried so hard to have a Japanese fighter fish i gave him or her a large tank yet i could never balance the water i really enjoyed watching it. A flaminco dance costume

[@Ozponds]

Same principles as a pond apply. Good biological filtration, if you want super low maintenance, establish a complete ecosystem

[@davidschaffrick3961]

Do you need bio balls or a filter screen in barrel with rocks for bog filter? Also in ponds I see bubbles coming up usually in middle of pond...what is that?...I thought that was pump, but in video you showed that the pump was in a different spot.

[@Ozponds]

You don’t need bio balls or filter screen in a bog filter. Bubbles are created by an air pump (outside the pond), there’s an airstone or diffuser on the end of a hose/tubing that creates the smaller bubbles.

[@davidschaffrick3961]

. thank you for your response. what kind of air pump would you use for about 1000 gallon pond? Where do you get them?

[@Ozponds]

@@davidschaffrick3961 I don’t but them based on the volume of the pond, I buy them based in depth. The deeper the pond the more powerful they need to be. I get mine on eBay.

[@AQUAGUYUK]

sorry to trouble you with this i do wonder if this bog /pond filter could be adapted for aquariums i only ask as been looking at your results for a while now and i have aquariums that use deep substrates and plants so wondered if this system could be modified to add more or a better filter to my tanks ,,,and advice would be appreciated and welcomed keep up the good work

[@Ozponds]

I believe it would be perfect. When I retire and I set up lots of tanks it’s going to be my method of filtering.

[@AQUAGUYUK]

@@Ozponds Thank you i may try myself your vids are inspiring

[@S0me0ne_S0meWhere_SaysHi]

You can buy bacteria from shops to get a filter working. Is this necessary or does bacteria naturally grow in a suitably designed filter?

[@Ozponds]

It grows naturally. It’s a funny thing I sometimes think there’s a benefit to adding bacteria or at least some filter media from an existing healthy pond or aquarium.

[@wethepheonix4329]

recommend using footage of what you are talking about rather than recycling footage. great information thank you

[@Ozponds]

Can you do my editing for me? It’s really time consuming.

[@MrJmhess77]

Hey, no fair! I didn't get animations in my bog build video! LOL! Update: My bog is working amazing. I discovered a small leak in my stream just before the water gets back to the pond so having to fix it today. GRRRR!

[@Ozponds]

Bummer. Good luck getting it sorted👍

[@vvoss2805]

I have used papyrus in a bog filter with rocks only. The plant doesn't look as good as its potted version, it needs soil. Thanks for the info

[@Ozponds]

I’d remove it anyway, if it gets going….those roots are full on.

[@JakeHe-c3k]

Hi, is it possible to build submersible bogs filter? I have a water fountain. There is no external pumping. What kind of filter do you recommend?

[@Ozponds]

You can, but it still would want to be sized correctly.

[@НиколайБондарук-й2и]

TY for your job❤

[@SherrickDuncan]

Will this work with a muddy looking pond lined with sodium bentonite clay rather than with plastic or rubber liner?

[@Ozponds]

I depends on how much sediment is floating around, clay can be notorious for refusing to settle.

[@SherrickDuncan]

@Ozponds what if I put sand down before adding water like the Fayher Fish tanks but in a pond?

[@Ozponds]

@@SherrickDuncan nothing will stop sediment accumulating. It will get stirred up if there’s movement in the pond.

[@d.w.evans1182]

Hi there @Ozponds, what are your views on Bakki shower filters? I’ve been trying to get an opinion on wether bog filters or bakki showers are the best, I assume they both do the same thing or are they both different? I’ve seen lot’s videos of koi keepers building their own showers and I’m now unsure wether to go with a bog or Bakki filter. My pond is approximately 6500 litres and has a mechanical filter, it’s got lots of plants and wildlife as well as fish but my water is dark, (I believe I have to much organic matter in it), so its not really a proper koi pond. My plan is to fit a skimmer with the water feeding the bog or bakki. Any advice would be gratefully appreciated thanks.

[@Ozponds]

There’s lots of different ways you can filter water. I like bogs they work, easy to DIY and blend into the landscape.

[@bingowashisnameo80]

Hey, I have watched a few of your videos on bog filters and was just wondering where you buy your pond pumps from? I am trying to find some that are decent quality that are 6000ltr a hour (I am in Australia also, Queensland to be specific). I am new to bog filters and ponds I am just trying to not buy a bunch of crap pumps to find a good one.

[@Ozponds]

I’ve been happy with the pond max evo range. If you buy them from rock around the block. ozponds.com/pond-equipment-australia/(here’s a link). Use code: OZPONDS and get 5% off. Hope that helps 👍

[@dcpathberiya]

Can we use a big filter for a swimming pool

[@Ozponds]

Many people do.

[@dez3940]

nice vid. could i sed you some pics and get your opinoin on a layout ?

[@Ozponds]

I don’t really have time to help people one on one. Therefore I try and focus on videos and articles that can help lots of people at once. I have vids on layout, hopefully they can help you.

[@ErossaanBooming]

What type of rocks to put in the rog filter ?

[@Ozponds]

Anything that’s cheap or I can get for free.

[@ryantait177]

thank you

[@skiphardin7259]

Will a bog filter work if I don't have fish?

[@Ozponds]

Yes

[@Allthingsni]

I have a large natural pond in my house that my Hubby & I purchased….. I know nothing about building this do they sell these 😮😮😮😮

[@Ozponds]

There’s lots of pond filters for sale, natural ponds are different to fish ponds. What’s required depends on what the issues are. You’ll either educate yourself or hire an expert.

[@scottdaniels3033]

Good video
