Bog building, also called upflow filter, eco filter, wetland filter

Thinking about adding a bog to my pond.

you will be happy with the results

you will be happy with the results

I think so as well

My pond stays really clear but I have alot fish waste that I want to be able to get rid of more easily this is the main reason I am wanting to install bog plus I will leave my waterfall filter system so I will then have 2 water falls. I am also going to hide my heat pipes since I fixed my shelf to hide liner plus reduce them to 1 inch so they heat better and will make life of heater last longer. I THINK THAT IS ALL FOR NOW

where's the pictures

I BUILT TWO bogs one peastone with 2" pvc pipe. and a second matrix bog my main bog the matrix is shut down. im replacing the liner to the larger bog get a larger waterfall as i had next to nothing from the bog. So my setup is now running off a small undersized bog water was chocolate milk and cleared overnight.

My pond is 1000 gal so how big of a bog do you think I need I was thinking about 125 to 150 gal or should it be less or more

Bog sizing is typically measured in surface area as a ratio to the area of the pond instead of gallons because focus tends to be on space for plants. I think it's probably useful to measure by gallons as well, but it's a less straightforward process and we don't have rules-of-thumb developed for that yet.

Just keep in mind that @ 1,000 gallons, you probably need to be sending your full pond volume through filtration about once an hour and you want flow through your bog to be slow. Probably at least 5 min. dwell time. More is better. So, at 1,000 gallon pond, you would need the bog to hold at least 80 gallons. Pea gravel takes up around 70% of the space of a container, so 150 gallons is probably the absolute smallest bog I'd build at your size pond unless I had other filtration.

I will be keeping my biofalls as well bog will be a totally different set up all its own but thanks for the feedback I appreciate all the info from everyone

Chilids are very picky about water quality and they breed worse then rabits. I am also a firm believer in over filtering so if there was ever a problem like my plants growing so much my stream backed up draining the water and I lost I think it was 5 koi 3 of which were good size they had a miserable death as the water drained out. I was on buisness .as the pump slowed the water refilled the area which was not the best as the ammonia was introduced to the rest of the pond. BUT THE BOG HANDLED IT I lost no fish that were in the main pond. The others were in holding waiting to go back to the pet store.

I would build as big as you can if nothing else it will handle the addition to your pond in another couple years.

I know I haven't stopped since I built mine.

I have already thought about making it bigger lol so I will keep that in mind for future

Started gathering parts today to build a bog. Does anyone have a bog system that filters 2 ponds just asking because I am thinking about putting a large enough bog to filter another pond and my already existing po d

Mine, technically, filters 10 ponds. The water communicates among all the ponds , goes through one bog.

So long as you Daisey chain the ponds you can do as many as you'd like technically. If your thinking one bog with two ponds and two pumps that from each pond a pump pushes to the same bog the answer would be no .

Thank you Addy1 I have plenty of room to add on so I am thinking of building big enough bog to filter another 1000 gallons so it will be total about 2500 gallons not taking away for water displaced from stone. Picture is the area I am thinking of adding.
