Actually, I rather like the longer format. For me, this one of your best educational videos as it had more information.

I honestly like the longer videos especially when they are packed full of information like this especially for when I'm doing a project I can reference 1 video instead of multiple videos! Thanks for the video!

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.

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).

Love all your videos, your voice is very calming to listen to. Long or short they are all great.

I’ve made 2 bogs like the ones from your previous videos and both of them have functioned perfectly and greatly improved my ponds water quality….thanks a bunch

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!

Having had problems with green water in my pond - despite using purchased pond filter with UV - I constructed a bog filter based on one of your designs. After 3 weeks the water is clearing and looking much better. Thank you so much for your advice and help and best wishes from Derbyshire, UK. Andrew

Thanks for another informative video Kev. Definitely not too long. As commented by others, the longer videos with so much valuable information are appreciated 👍

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

great video, i also like the longer format because it has all the relevant steps in one go =) really excited, we are building our first pond right now, about 3000litres, and because of your input we decided to go with a bog filter - fingers crossed! ^^ thank you for all the very useful information!

Another enjoyable and informative clip. Thanks Kev. I tickled the thumbs up 👍 button to feed the algorithm monsters.

Thank you for your work. I built the filter recently and after 3 days water in my pond was clean and clear. I’m shocked how quickly the filter cleaned water. Greetings,

Excellent video Kev!!! Everything is explained beautifully in this video. You are the master of DIY Bog Filters! Thank you so much for sharing all your knowledge on this topic. ❤

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.

I made two for my small pond that looked like pea soup. In two weeks it was crystal clear. Thanks for the videos.

Thanks for ALL your help on my bog filter. It has been running just this spring and its working!!!!!! All Algea is going away!!!! U r awesome!!!!

Never worry about the length of the video, i think it was very informative and i'm going to try to build a filter like that. Thank you!

Grateful to this video ! Reviewing the basics and more!

As always Kev, another very informative video. Not too long at all. Thanks again.

Thank you for the information. Your work looks great. The "long" format is needed.

Bog filter here we come!! Thanks Kev. 😊

You answered so many of my questions in this video thank you thank you.

excellent information once again

Great video, not too long at all. Gives me confidence that I can do it! Thanks

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.

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!

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

nice video keep them coming

I'm so excited to make my first of many. I feel really confident after watching your videos. Thank you 🎉

Thank you for another great video!!

Thanks for the information.

Kudos on the good video.

Thank you for your knowledgeable guidance! I have a large size problematic pond that I will try to place the addition of a bog filter onto with your guidance from the videos. 😬🤞

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!

Great video Kev! Thank you. We are still working on reconstructing filtration for our 6000 gal pond. Previous owner used fish netting in two large tubs. Bog is better.

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!

Good video

Thank you for your videos!! After years of green, I'm going to try this straight away! The pond is 10' x 14', about 3' deep that houses 4 good size turtles. 2/3rds is below ground & 1/3 above. There is an island, so I estimate about 1,400 gallons. I will build a 250 gallon bio-filter off to the side. The top of the bio-pond will be higher than the pond, though the bottom won't be. The pump is 2,800 gph.

Been watching - and rewatching your vids....thankyou for sharing your aquired expertese....just starting my own project and I am grateful for what I have learned...I wonder if the same techniques can be used to clean up politics

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.

Your vids are so clear and well made. Would tadpoles or newts get sucked into the pump that pumps water to the bog (and die)?

Yeah I'm on eBay now getting my water plants for my filter bog 👍

Excellent video, definitely not too long. Building a bog filter for a 250 gallon pond with 5 gold fish for my 81 year old mom. She has had the pond for a long time but the small commercial filter is not and really never has worked very well. Doing a 20 gallon bog with a 200 GPH existing pump. Is this pump more flow than necessary? I plan to have the pump across from the bog filter return waterfall. Would you recommend a skimmer with this size pond. Thank you in advance, Frank

Hey Kev. Love the video. You have inspired me to redo my pond. It was initially a great idea but! The sides go straight down. Big no no. From experience the mini cog’s you’ve planted are beautiful but they drop dead foliage underneath and it falls into the pond. I’ve noticed there is only one close to the edge of one of your ponds mine lined the whole pond Such a mess. Ill print out your pdf when im ready for working that out. ❤

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?

Hi, Well I have done it!! I have used a water butt - it has not been easy (a bit dim!) but it is up and working......just got to put in the plants. I love your videos and the length does not both me. How long do you think it will take to help the water? It is a large butt (2000 lt) but the pond is 18000 lt......Just fingers crossed this helps my kio and pond.

Love your very informative videos. I have learnt allot. One question, I am currently building an above ground pond and looking at building some filtration. So can you just have a bog filter and not have to have mechanical filter along side. It won’t have KOI but just gold fish etc…

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.

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.

I have a 5 acre pond with an average depth of 7 feet. Do I need multiple 750 gallon open tanks? I think estimate is 6.5 million gallons of water.

Hi Kev, is it possible to operate multiple bog filters in a row? Say one barrel is 50 gallons, the second barrel is 30 gallons. The water runs through both barrels before flowing into the pond again.

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.

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

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?

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!

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.

I have converted my 50,000 l swimming pool into a pond with some fish and plants. I’ve created two small bog filters because space doesn’t allow the size you suggest. Will adding something like diatomix help with algae?

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.🤔

Fix the typo in the title please. "crystal". Make a great weekend !

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

What plant is that in the filter?

Can you recommend some pond pump brands that are safe? I am afraid of electric shock on my turtle from random brands I find online😂

blows my mind why so many people use cheap toxic chemicals that do more harm than beneficial

I work professionaly on ponds and the local norms say a bog filter is not a real filter so you get fkd by the law if it doesnt function and you get sued. Sad reality

No one believes me that my bog filter (thanks to your channel) has cleared up my green pond water. 🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔😕😕😕😕😕😕😕😕😕😕😕

Having had problems with green water in my pond - despite using purchased pond filter with UV - I constructed a bog filter based on one of your designs. After 3 weeks the water is clearing and looking much better. Thank you so much for your advice and help and best wishes from Derbyshire, UK. Andrew
