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 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!

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

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.

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!

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).

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

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

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

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!

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

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!!!!

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.

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!

Hi Kev. Thanks for keeping the content and inspiration, flowing. And making the info crystal clear. ❤

Another enjoyable and informative clip. Thanks Kev.

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

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