There is great value in these step by step practical videos. I am so tired of watching pond videos that teach so little and work so hard at impressing us and wowing us with superficial walkthroughs. Thanks for the real help.

If you use lava rock/scoria for the pebble layer it will significantly reduce the weight of the filter and the porous nature of this rock greatly increases the amount of surface area for nitrifying bacteria to colonize, thus making the filter more effective for its size and weight.

Just dropping a note of thanks for this video. I made my own bog filter a few weeks ago and my pond water is already looking awesome. Really appreciate the content.

Not boring at all. I'm using these concepts to design aquaponics systems!

I have watched your videos on bog filters with interest. We have a pond here in NZ with a volume of 1000litre . After trying for for some years to get our pond clear I decided to follow your design for a Bog Filter I purchased a 100litre plastic drum and removed the top then built it to your design. The pond Pump is a Davey Pond 7000. Plenty of flow to which I have restricted by a valve setup to achieve the required flow thru the filter. The pump also supplies a rock water feature as well. Within two days I have noticed a considerable change in water clarity and the boss(partner) is very happy with the outcome. Thank you for the information you have provided. The only problem I now have is the disposal of two redundant Sponge type filters.

I made this for my pond about a month ago. My water is crystal clear now, I’m blown away by the results. Thanks Kev

Hey Kev, I've probably watched this video 10 times... build my own bog filter to your design and it works like a bomb! Love your channel, helped me build my 1st pond and filter - and it's a success.

Hello Kev, thank you so much for sharing your knowledge. Some people will not share information which is sad as we all want to make this world a better place. We have struggled for years with our pond, and this was the last attempt as we were ready to get rid of it altogether. My husband followed your plans, and we now have a beautiful clear pond and frogs.... wonderful!

Your videos are the best: simple, direct, to the point and easy to follow. Not to mention, this filter actually works :-) Thank you so much for creating quality content!

Thank you so much for the easy way to help with my large tilapia/prawn pond. I live on a very remote island in Fiji where water and power is captured and solar making water saving a priority and this has been a huge water saver for my pond. I was close to giving up on maintaining my pond until I stumbled on to your video! Thanks again,

Thanks mate. This was so helpful! Perfect detail and tempo

Excellent presentation, straight to the subject, easy to follow, useful, well narrated. Thanks!

Thanks for your videos! I’m amazed at the difference in water quality with my bog filter running for just a week!

Simple, but yet so sophisticated in how it works!

Best bog video I have found. Thanks mate

Thank you. This is the first video that explains just about everything I needed to know. This system is perfect for my little project

You explained this in so much detail, that I subscribed on the spot. I have two 110 gallon hard liner ponds, and this video convinced me to finally proceed with their proper installation. Gracias. Greetings from México.

Your video is amazing. Very simple easy to follow. All the others I have watched is rather complicated and confusing. Thank you.

I have a 2000L pond with a mechanical pump and filtration system but it just wasn’t cutting it. With the space I had available next to the pond, I built a 100L bog filter to work alongside the mechanical and boy the results are AMAZING! Super clear water, I can even see right down to the bottom at 1m depth. My system works by the pump from the pond, into the filter to collect the larger debris and then into the bog filter. I installed this towards the end of summer (August in the UK) so I’m looking forward and hoping that when spring comes along the results will still be just as amazing when the water starts warming up and the algae starts blooming. Thank you Kev and keep up the good work!

I am just building my own pond and I am so glad that i found your channel! You helped me very much in planning my own bug filter and a little waterfall coming out of it. You also safed me a lot of money :D Thank you very much! Greetings from Austria (Europe 😄)

I’ve learned so much from your videos! Thank you for helping me work towards finishing a long-overdue project! 2/3rds of the way done now.

Most useful video for DYI pond filter. So much USEFUL info.

Boring? No way!!! Thanks it was fascinating and very helpful!! Thanks!

Love your thinking on this - particularly the drain valve as I can use the waste on my garden. Beats cleaning out my sponge bio filter. Very ecological, plus a great water garden into the process. I'll be using a large pvc water tank (disguised) - Ralph (UK).

Thank you for the guidance. Keep up the good work.

Amazing video! You’ve inspired me to try to build a bog filter now.

Thanks Kev, your videos on bog filters has been invaluable and our exchange of emails has enabled me to build a filter that actuallt works! Years of using UV and sponge filters (none of which worked that well) now I have clear water for the first time. Great advice mate.

Thank you so much for making this video. Your instructions are so clear and easy to follow, I'de been fighting with a crappy little filter for too long. Made this bog filter like a week ago and it is absolutely amazing. I can't believe how clear my water is and how easy it will be to maintain. Thanks again!

Covered the important pieces really well- thanks so much!

Thanks mate. You inspired me to build a bog filter using a planter that i had lying around. I've now also got loads of watercress growing that I can eat. All the best from the UK.

Thank you 😊 About to build a new pond and this is brilliant.

I finished my first 60 ltr Bog Filter last week and after 5 days I already seeing improvement in water clarity. Thanks for the videos.

Thanks for the guide Kev. Simple and most effective method to achieve crystal water in the pond. I followed this guide and had my filter running 3 weeks ago. The plants are still bedding in and already, the results are amazing. Didn't really know what crystal clear was until now. The pond is healthy, the fish are healthy. Your explanations in your videos are very good ranging from practical guides like the bog filter and also the science of the nitrogen cycle. Awesome, thanks!

All I can say is that it works. I made a small waterfall with a 60 liter pond and the filter according to your idea, has been working for 3 months, the water is clear and small creatures have already appeared in the pond. I use a solar water pump that works during the day when it is sunny and for another 5 hours on the battery, however the water is clear. I made the filter from materials I had at home, but the construction method is the one indicated by you. Ohh I forgot to put the drain valve 😆 maybe at the next bigger pond. Thanks from Romania.

Very nicely presented information mate. I really appreciate it. I am going to take your suggestions and make a bog style filter that will flow back into my small pond. My wife will appreciate the sound and the plants, fish, and I will appreciate the effectiveness and simplicity. Cheers

Such a good description! Thank you.

Great information. Im in Canada and going to attempt to clear up my 1/4 acre pond. Thanks

i used your design to build my bog filter. I got my uniseal in really easily by droping it in hot water for 30 seconds. Also, i left out the glue. I didn't know how to use it, but the filter works great. I built it last year and its still works.

This is the most helpful video I found thank you!

Great video.. I have several ponds.. I believe bog filters work very well. Thanks for sharing..

This is such a great instructional video. Cant wait to put this into action. Subbed! ☺

Hi Kev. Awesome videos. Nice and clear. Just installed a bog filter following your advice on my 2000l pond and it went from pea soup to crystal clear in 9 days. So pleased. Many thanks and keep up the good work

Thankyou Kev for the info on how to make this bog filter. In the process of making this as we speak . Purchased all the material from Bunnings nice and cheap as I'm living in Oz . Great videos ,subscribed . Cheers Greg.

Hi Kev. Just wanted to thank you for this video. I watched it at least 10 times and finally got the confidence to build one myself. Mine runs on a solar pump. It looks awesome and the fish love it! Still have to find a plant for the top. My neighbor wants to make one as well! Thanks-Carol

Thank you for sharing I did same thing and it work really good My big problem is finely finished now my pond is clear water .again Thanks

Awesome idea, I have a 3000+l pond might try this in the future

I’m planning on adding one of these filters later on down the line. This is a pretty simple way to do it. I water my vegetable garden from my pond. My plants have shot up from all the nutrients.

Hey Kev! I just wanted to say a massive thanks for these videos. I have a 400+l pond which is just under a year old and when we had some good weather here in the UK recently the water went that typical green soup colour. So I set up the barrel bog and built it like yours and it took a while before I got any results and that was because of the flow, once I slowed it right down like you said in just a few days I had very clear water. Absolutely amazing how well this works, cheers mate!

Thanks for the vid! It only took 3 days to have crystal clear water and it's so easy to clean. Pond holds a turtle, local plants and 10 gold fish. My pump is a bit overpowered for my 250 gallon pond, so I used a full 55 gallon water barrel. I had to make two out flow holes 3/4" with flex hose each because my pump is so fast. I haven't even filled the barrel completely with rocks yet, only filled about half way and it works perfectly.

Top work bud.

am planning to build the bog filter this weekend. the bottom of my 'bog' will the same level as the top of the koi pond. we have a filter we got from amazon, but after seeing what u built i want the water than comes out to go into the new bog i am going to build. i will add sedums, possible a lily plant, even some oxygenating plants if i have any left over from my shrimp tank

great info in this video :) nice care to details, not only about how to build a bog, but how they should function. and great execution to top it off. nice :D

Thank you and thank you again! Your video may be the most complete and helpful and simple I've ever seen. And you also tell us where to buy the parts. I like cheap and inexpensive. Too often I see pond supplies being touted as must have and being sold for over the top prices. Thank you for the drain information too. I wonder if you have or could make a video about a short (1 to 2 meters, 6 feet) on the surface very low flow stream. Thanks again!

amazing man! very nice!

Thanks for such a great video. I'm.in Katoomba so temp us challenging . Thanks again for such a great video

This has helped my pond so much, thank you !!!

Nice job

Ozman! I achieved clarity! green water, through a rock based filter, now crystal clear over... a week? I also have a sponge in it that had established bacteria from an aquarium to kick start. Thank you so much for your hard work!

Thanks for the detailed breakdown, mate. We're looking at making our first pond (~2500 L) and stumbled on to your videos. I love the idea of a natural filter system. We're looking at ways of implementing this with a small waterfall feature.

Thanks a lot for this video. I am in the middle of setting up a small pond consisting of two half barrels at different heights so the water falls from one into the other and a solar powered water pump to complete the flow. The idea is to have a few plants and a couple of goldfish. I was looking for an idea to filter the water and I think it is small enough to try a similar system using a terracota pot instead of the olive barrel

You are awesome! Easy explanation

You make the best videos, thank you!

One of the best videos i too have seen.

Wow, My best friend, I liked the video very much, thanks you for sharing, stay safe, stay blessed

awesome video✌✌

Thank you so much, this is really useful. Cheers

Thank you! Lots of helpful tips and good info

Great video mate, im gonna make a bog filter for my pond tommorrow, cheers yeti 🏴󠁧󠁢󠁳󠁣󠁴󠁿

Hi I've made your DIY bog filter design just over a week ago and it's turned my pea soup water into crystal clear like tap water in just over a week and I'm totally amazed by the results 5star advice 👍 P.S and without any chemical additives.

Thank you

Thank you for your Chanel you are a amazing. I can’t wait to try to build are own bog filter for are first pond

Thanks for the shoutout mate. Let me know if you're ordering again & I'll sort out a bit of a discount for you. 😉 Nice looking filter. I know folks that use something similar in aquaponics. Cheers & have a top one Kev.

Thanks great video

Thank you.

I'm planning to do that ! look so awesome

Great videos, great ideas! Might use some of them. My little pond contains about 55.000 liters so I might have to scale up a little... 🐟 Greetings from Sweden!

Nice job man

This is a great video!!! I have way over kill of a bog filter. Yet my water is thick like pea soup! Flow rate was the issue. Bigger is not better.... Clear water now, perfect! Thank you

this is very cool!

Thanks for the primer. I'll "try not to get too bogged down in the finer points" ;-)

Wow, best advice ever! I also didn't know you could put any plants into the filter. I guess impatients are good. I'm not sure what good plants for the pond are as my fish are nibbling at the weeds on the edge. Would like natural plants when I bring them inside soon.

I've used cardboard with only mulch on top like a biodegradable landscape fabric. I cut holes in the cardboard and plant beneath it. I do like contractor paper though. I find it easier to overlap and keep edges clean. I have it under my beds, heavy landscape fabric in walkways.

Awesome design, great tips and advice. My brain jumped ahead to a chain of these filters with my herb gardens and veges growing in them. My family is living out of a car at the moment so might be a while eh😂

Great video. Thank you!

Made a filter similar to this, works great, now clear water, before there was no filter and water turned green every summer.

Brilliant

There is a valve called a "vacuum breaker valve" that is used in irrigation systems to allow air in, in the event of the need to break a suction occurrence. Quite cheap and common.

Thank you 🙏

Hi Kev, good news I got my pond and for the most part the stream dug out today, it's a 7x5 with a depth of 3 feet (sorry). I also picked up my barrel container and have started on the construction of the bog filter. So far so good, no issues and everything is coming together nicely. It has to at this point as my wife will kill me if I don't end up with water in this giant hole in our backyard! HA HA! I have to let her sweat it out a little bit. The PDF has been really solid reference to use. FYI - I built a mall pond years ago so it will be fine. The filter was much easier than it looks.

That guy Ian is lucky eh, having nature do it for his ponds.

Understood. Thank you much.

great video, thanks!!

I'm going to add a bog filter to my two stocktank ponds, one 100gal the other 180gal, to combine the water and biofiltration... i'm worried about backflow into pond if we have power failure (common during summer storms here). Was initially thinking of a flowcheck valve on the input lines, but your air hole approach may be more effective/easier!

Thanks!

Is this the only filter point of your pond. Wow!!

Awsome vid mucker 👍🐟👌

Like I mentioned below, great, amazing video... By the end, you showed how you clean... Just wanna double check... You don't touch the rocks at all, eh? Just open the cleaning valve and wash from above?! Once again, thank you!!!

thank you for this video

Hey Kev! The Dream pond looks fantastic!

This is a great idea, it's inspired me to think up new ways of filtering my pond using the surrounding stones and rocks acting as both filter and scenery. Quick question, can a filter ever be too big? Or does size not matter as long as the flow rate is correct?
