Bog filter overview and cleaning

[@nailer65]

Another great video Kev. I used your past videos as a guide to making my own bog filter based on a 45 litre storage box that I keep hidden under some shrubs nearby. I made a couple of modifications of my own. Firstly, I have an old pressure filter that I bought a few years back to filter solids before the water gets to the bog filter. That way I can clean out solid waste more often without having to go near the bog. Secondly, instead of having a breather valve, I just drop the feed hose into the top of a wider pipe that then carries the water to the bottom of the bog. A bolt running through the downpipe prevents the feed hose from going too far down, so no risk of sucking out the bog if the pump fails. Keep up the good work Kev!

[@Ozponds]

Awesome. Love it! 👍

[@michealadderley9081]

Thanks for sharing another video how the bog filters work so well keeping your various ponds so clear and natural looking and the ease of maintenance is surprising lot less than having to clean filter brushes . Media . Etc

[@Ozponds]

I’m pretty lazy by nature. I don’t mind putting in hard work to set it up but then I just want to enjoy it. Some people get enjoyment from tinkering around the pond cleaning filters etc.

[@Sandra-Armstrong]

I got my first stock tank yesterday!!!! Yaaaayyyy... I can't wait to start building ponds!!!!! 🥰

[@Ozponds]

Awesome!! 👍

[@RyanDonnard]

Thank you for highlighting the need to clean out the bog filter top down. I had enough detritus caught in my bog barrel that it nearly overfilled. Will need to clean the debris found in the stone and top down spraying is exactly what I needed as well. Cheers, keep up the good work.

[@RodCornholio]

Really appreciate all your content. About a year ago I made a couple of container bog filters based on your design. I used solar power for the pumps in one of them. Works great. No chemicals and pretty low maintenance.

[@Ozponds]

That’s great to hear 😊👍

[@elmohead]

Just a small tip regarding colour: look up Disney's Go Away Green and Byebye Blue. Use these colours to make unwanted things blend away into the background.

[@Ozponds]

Thanks for the tips!

[@samchanning22]

Great update Kev will come in handy when I clean mine out in spring next year as we are just getting ready for winter but the bog is looking great after 6 months and my water is so clear even with the koi eating like crazy. Putting a bog filter in was best decision I ever made 👍

[@Ozponds]

That’s great Sam. Glad to hear the pond is doing well 👍. I gotta be honest I’m pretty keen for some warmer weather.

[@samchanning22]

@@Ozponds ye really good thanks just catching up on all the vlogs of your new pond build it’s looking good 👍 and not far of 25k subscribers now good to see the channel growing mate great stuff. We have had a really hot summer in the uk so I’m happy it’s getting a bit cooler now give it a month and are be wishing summer was back can’t wait to see everything in full bloom with your ponds 👍

Comment for support. I like your content

[@ansleybleu]

One thing, in my opinion, that you should add to your bog design is a clean-out valve for the intake pipe going from the pump to the bottom of the barrel. I just tried cleaning my pump and the intake pipe was so clogged with muck I had to rip it all apart. It was so frustrating. I still have to put it back together am not sure if I have burned out my pump yet or not either.

[@Ozponds]

That’s no good. I don’t glue most of the components, so should be easy to pull apart, although I’ve never needed to. I think it helps that all my water flowing to the bogs is pre-filtered by the skimmers or intake bays.

[@moomoon1410]

Thank you for this amazing video! Couple of questions please: when to know filter needs to be cleaned? Can a dirty filter explain a sudden change of the quality of the water? Does the distance between the pump and filter matters? I would appreciate your feedback. Thanks Kev!

[@Ozponds]

I tend to clean mine when I do notice a change in water quality. Distance between pump and filter doesn’t matter so much from a filtration perspective. Having said that you want to position the pump on the far side from where the clean water returns, this improves your circulation. The further the pump is from the filter the more pipe work you need and that can reduce the amount of flow the pump can produce.

[@moomoon1410]

@@Ozponds so if I understand you well, a slower flow is best. Right?

[@Ozponds]

That’s what I find. There’s plenty of margin of error room.

[@n072120]

Hey Kev, built a bog filter 12 months ago and it worked great. Planted impatiens and bacopa in the top. BUT… when I went to do the first yearly clean I found the plant roots had thrived growing right to the bottom of the filter and all through the rock. So much so that the stand pipe was just about chockas with roots. Not as easy to clean as just opening a valve but I have to say that the roots provided great filtration. Did you ever have this problem ? What was your solution? Thanks Darryl

[@Ozponds]

I’m guessing this is a mini bog if you have a stand pipe. My original mini bog filter is 7 or 8 years old, still has one of the original impatiens. I twist the pipe that creates the guard every now and then, that breaks off the roots between the guard and the standpipe. Hope that helps 👍

[@Shmaybe]

Get video once again. Regarding the breather valve, could you use a swing check valve? or could build up stop it from functioning.

[@Ozponds]

I find they fail after a while. This filter initially had a check valve then I replaced it with the breather.

[@Shmaybe]

@@Ozponds good to know thank you. I was wondering if they got all blocked up.

[@SzerdzsoCortez2]

What is the function of the void space above the bottom of the bog (above the centipede modul) build from pallets, crates or aquabloxes? Does this bottom trench where the centipede modul lies essential? You have none of these. These only make the bigger bogs easier to clean?

[@Ozponds]

I use the bottom trench but not the aquablox or pallets. I still want a void space where the water enters and solids can accumulate. My bogs are narrow so I feel the aquablox/ pallets are unnecessary. If I were going wider then I would most likely incorporate them. So yes the void space is mostly essential for cleaning, it does also play a part in allowing the water flow to spread out. I hope that makes sense and answers your questions.

If I allow rainwater from a roof gutter to replenish the level in my pond, will I be washing away too much bacteria?

[@mingv4151]

Hi Kev, I see you use solar around your pond. Can you do a video to show how to set up a pond pump using solar power please? Thank you. Ming

[@Ozponds]

Those are just cheap solar pumps. Nothing to set up. My latest pond will run entirely on solar. I will show the set up once I work out what I’m doing 👍

[@matth4520]

Great video, just curious if you loose lots of water to evaporation, if you do do you have a top up?

[@Ozponds]

None of my ponds have auto top ups I prefer to do it manually, although one does get topped up with rain water off the roof. In summer I usually need to top them up.

[@danielfinch2611]

Hi Kev, just found your channel and love the content, keep it up👍 I’m interested in converting an unground swimming pool into a pond/swim pond and was thinking your bog in a barrel would be a good filtration option as it is scalable. Love to get your thoughts on this or to see a video maybe for some future content. Cheers mate

[@Ozponds]

It’s definitely scalable 👍. If I were to do it on a pool I’d be looking at IBC’s or stock troughs. Unfortunately I don’t have a pool to personally try it on.

[@NopeAndYep]

Great video Kev! Do you have a channel for your plant nursery?

[@Ozponds]

No. We sort of tried one based on propagating plants for profit but it was a bit of a flop and took to much time. I really love ponds so it’s easier for me to create content around them. I also love when people reach out and tell me that a certain video or design helped turn their pond around. That makes me smile 😊

[@NopeAndYep]

@@Ozponds I understand that! I love plant propagation, but many equate it to watching paint dry.

[@marnez390]

I did this method with a large olive barrel sized container and I've had it running for about a month now but my water is still dark green. The water coming out is almost the same color as the water going in. My pump is small enough to make the water coming out have a slow flow. What am I doing wrong? Do I have too many small fish? My pond is about 300gallons and I have 1 turttle and about 1000 feeder fish in there.

[@Ozponds]

Probably. Filtration is always a balancing act between bio load and bacteria (or something else that will deal with the nutrient produced). I personally wouldn’t stock 1000 fish of any size in a 300 gallon pond, unless I was willing to perform water changes and regular filter maintenance.

[@whileriding]

What do you use your solar panels for?

[@Ozponds]

I’ve got some solar pond lights and a few small solar pumps that help push water out of some of the areas where debris gets trapped.

[@whileriding]

@@Ozponds I have a small stock tank pond that I hooked up with a panel and battery. It works pretty well so I was wondering if you did something similar. Great video btw!

@ozponds how often do you flush the bog filters?

the down stream could work as the whole bog? or this specific one is too small for the pond and u built a barrow bog to flow then to the stream then to the pond?

[@Ozponds]

Sorry I don’t understand the question. Streams will provide some filtration, just not as efficient as a dedicated bog. Hope that helps.

@@Ozponds im a pond newb that been searching a ton and learning even more from ur channel. if i'm not wrong i saw a video exlpaining how you can build a bog in the shape of a stream that can have the end of it as a waterfall, so all the bacteria on the rocks and pebles, plus plant roots filtrating while the water flow throught the long stream. i was dreaming of building a decently deep pond with an intake bay at the edge, then take most the dirt dug out to the side and build a taller stream shaped bog kinda circling around the pond to a waterfall on the oposite side of the intake bay. just one pump system, completly natural filtering. would that be a possibility? or the bog would need to be shaped like minipond at the start to filter from down up with layers of rocks and pebbles before moving downstream?

@@Ozponds ty! i've had watched that one previously, but on the first watch i didn't pay much atention to the bog piping part, gotta admit it still confuses me. from what i see u use one pump at the intake bay, and another pump on the bog? i was thinking that one pump on the intake bay getting the water through the pipes to the bottom of the bog, then up the rocks and pebbles then down stream would do the trick. i personally have trouble to visualize piping properly ^^' a video of you draining that specific bog and cleaning while explianing the flow of water through that pipe system would be awesome!

[@Ozponds]

Only one pump for the bog. Both ponds are inside the intake bay. One supplies the bog the other the headwaters of the stream. When I clean the bog I will make a vid 👍

Can i apply this bog filter method to my cannister filter for my 30gal tank ? Would it work as same effective ?

Aquarium canister filters usually have a high flow rate through them. Bogs need slow flow. You are more than welcome to experiment and see what works for you 👍

How big bog filter need to be for a 1500 pond

Usually I drill a bunch of holes in the outlet pipe. Let’s the water and fine debris pass through but not any rock or pebble. Always test it before walking away, just to make sure it drains freely.
