What’s the best pond filter? 

Just love this channel casual but informative. Love your passion kev thanks for all your help

If I understand correctly, bog is just exactly what it says, a barrel with a hole where water is pumped into, rises to the top through gravel or filter media and comes back to the pond?

bog filter

Thanks Kev, bought ur PDF out of support !! Glad you made all these videos my turtles are happy

Kev, thank you thank you thank you. I’ve watched endless amount of videos trying to get my head around the bog filter / pond thing and only now, after coming across yours and watching few, do I finally really get it. May be a touch of me expecting it to be very tricky but your calm, no fuss way of explaining, along with the exquisite (and beautifully understated) results of your work just clicked straight away. I’m a subscriber for life. Please keep up the the exceptional work and big kudos to you for all the effort you put into both making the videos for us learners and your fabulous ponds. 🙏🏼

Love your channel and content. Thanks for what you do.

Would you do a video with recommendations for livestock? For example I'm building a duck pond, whereas the whole pond is aimed to be a big filtering system. But I want to pump the water into my chicken run through a trough-like system of pvc pipe. Is it just too unrealistic with the ducks? Everything I've read says you can't filter a duck pond but I don't want to give up

I set up my 300 gallon stock tank pond about 4 weeks ago, and I used your bog in a barrel design. It only took about 2 weeks for the green water to clear up! I still haven't put fish in, because I want to make a cover I can put on at night and take off in the day time. There are too many raccoons here for me to leave it open. I am enjoying watching all the tadpoles right now, anyway. lol

I’m about to start the long process of planning out my first pond build. I have all of these feed buckets for our cattle laying around and I’m thinking about trying to use those for the bog filters. I reckon that are about 15 gallons in volume.

KeV, for quality water is fish needed? My family would like to swimming in the pond and as vegan we would like to avoid buying fish. Love your videos!!

Does the bacteria die when you completely drain the bog filter for cleaning?

I took your advice and built a big filter for my 5000l pond. I used an old 1000l IBC cut off the lid and filled it with rocks. Bigger rocks first then layers getting gradually smaller and gravel on the top. I have lettuce, strawberries, melons, impatiens, and cala Lilly growing in the filter. The filter also has a system of drain pipes to aid cleaning. My pond is now crystal clear and my fish are very happy. Cheers Kev thanks for your advice. Top bloke 😉

Would a IBC tote turned into waterfall/bog filter work .. thinking of putting 2 together and piling up the dirt around and making a water fall

Thank You!!!!I I'm currently bingeing all your videos here in Santa Barbara. Good job!! I care for a 5000 gal koi "formal" pond, with in pond gravel filter. Some other smaller ponds too. Big pain to clean due to access and depth (square pond 4 -5 ft deep) and keep water clear. And now, after many years of just goldfish young fish, the koi decided to raise some of their own, so filter load is increasing. I have four 250 gal food grade containers which Im thinking of applying your bog filter method too. Also have some 50 gallon plastic drums I might practice on. Whats your thoughts on the plastic fiber mats instead of rock,gravel, sand? It would make a big wieght difference as Im thinking of having sort of a "portable" cleaning filter, to back up the in pond gravel one. Maybe help pull out some of microcloudiness..... thank you again for your efforts..

Hey kev. Would you suggest shutting down the pump while cleaning the bog out? Let the debris settle before flushing? Or doesn’t it not make a diff? Thanks mate

Thank you for the links to the submersible water pumps. I have an approx 2000 Gallon pond, I plan on building a bog filter in a stock tank, do you recommend the hugger 800gph or should I get a more powerful pump? Thank you! I have goldfish, koi and rosy red minnows in the pond.

Thank you so much for sharing ALL of your knowledge over so many videos. I would really love to hear your thoughts on davidpaganbutler's (not sure if it's really "his" idea) pond filtering system? If you are unaware, to summarize, it's the reverse of your bog filter. Your filter moves water UP through the bacteria/plant area, his moves water down instead. He uses air pumps to generate flow, air enters the pipe deep underwater, which pushes water upward, while also pulling water from the pipe buried under the bacteria/plant/rock area. I love both ideas, but just want your "two cents". Thanks again for sharing so much knowledge!

Hello Kev! Thanks for all the info! Do you use those variable frequency pumps on swimming ponds as well?

Hi , is one single bog filter that you using? Is that enough? Or there are mechanical filters too? (Sponge filters)

Any thoughts on adding mud from the swamp to the bog filter to speed up colonization of the bacteria? I've almost finished digging out the pond (10' x 15' x 4' not including intake / bog) and hoping to have everything running by the end of the long weekend.

How would you design a bog filter with multiple pumps? Just in case one goes off, it would be good to have several of them running, and you can further adjust the flow by switching some of the pumps off. I wonder if there are any tricks I need to consider.

I built my first bog filter today! I am so happy with how well it is working> I have had it running for about 5 hours and the water is already looking cleaner. Thank you so much for all the information I have gleaned from your website. I feel like I am finally making some progress. Thanks again : )

Hello mate, thanks so much for the info and effort you put in your amazing channel! Please do tell, if I make the bug filter on the bottom of my pond not separate is there a problem? Thanks cheers.

I am so glad I found your channel. The people that built the pond at house I bought had no filtration set up. Just a pump with fountain, in the corner of the yard with the most sunlight As I added a waterfall to cycle water and learnt more talking with local stores. I still had a lot of trouble with the green water algae Draining and donating fish wasn’t helping enough So I made a make shift stream, got some cheap mesh filters from Amazon I placed in my waterfall, bioballs and a bunch of rocks to fill the stream Within a few weeks my water is the clearest it has ever been in the 3 summers I’ve lived at this house I didn’t even do a big bog filter in a tote/barrel with the math you said and I am still noticing a huge improvement I have recommended your channel to others

Hi dude you do such amazing work. I am a newbie and teaching myself good or bad. I was interested in your opinions on adding sand to an existing above ground pond with some plants and fish. Is there a benefit to this or no? If so what is the best method for doing this?

Amazon link is taking me to breast pumps 😂

I like the K1 3 barrel filter. easy to clean and install.

i m about to build a new 30'000 liters pond, how strong should be the pomp?

When creating the bog space, can I be cheap and use old milk crates, or will that bite me in the fourth point of contact later?

Things always work out once nature kicks in. Thanks Kev, make a great weekend !

Aces as always.

Thank you

Thanks a lot for the information and the links.

Thanks for all of your fabulous content.

🐠🐟🐠🐟👍🏻🍻

Kev is there an issue with oversized bogs? I am thinking of growing edible veg from the bog.

Hi Kev ,thank you for another great video. I still don't quite understand how you size the pump. Say you had a bog filter as big as 70 litres your pump would be 6 ×7 so 42 . But 42 what ? 😊🐟🐡🐠🙋‍♀️

Maybe, just maybe .. all those left over face masks from that whole stupid covid thing could be used to turn into a filtration system. 🤔 Hmmm, leave it with me, I could be onto something here.

Can I get away with a bog 10% the size of the pond if I have an additional, connected smaller pond that will only be for plants? So my plan is these things connected in order: Bog filter, 450-gallon pond with only plants and tadpoles, then a 2000-gallon pond with a conservative number of goldfish and koi. The only reason I ask is I’m having trouble finding a stock tank bigger than 250 gallons (10% of my total planned volume) where they will ship to my area without a ridiculous shipping charge. But I do want to do this right. Thank you!
