Hello, I just purchased a new bio -filter. I have not yet installed it, as I want to make sure it will be the appropriate size for my need. I have a small home made pond ( rubber liner and about 300 gallons). We have 7 large Koi and feed them almost daily during feeding season. The bio- filter I purchased is the VIVOHOME Pressurized Biological Pond Filter, 1840 GPH. Is this a fine enough Bio-Filter, or is there something more appropriate I should consider?

7 large koi in a 300 gal pond to me seems like an issue. I don't have koi, just goldfish but have heard the people here that do say that maybe 500 or more gals are needed for just one koi. Hopefully someone w/koi will chime in here to help you.

I agree. After raising koi and selling them for over 20 years your pond is too small. You need to start building a bigger pond before you start having issues.

Hello and welcome!
It sounds like the size of the bio filter is adequate for 300 gallons, but I can’t speak to the filter itself (no experience with pressurized filters), expect to say that with koi…..you need the most filtration possible! Agree with the others that 300 gallons is too small for even one koi. Just curious, but could you show us some pics of your current setup?

Welcome Becca...Hopefully someone with bio filter knowledge will chime in. Good that you are concerned. You might think about rehoming your koi and purchasing Shubunkin goldfish (they are so very colorful and grow large). Koi put out A LOT of waste and 300 gallons is not even big enough for one. Hopefully you have a liquid test kit, if you don't you will need to purchase one. Your koi must be on the small side if you aren't seeing any problems so far, but unless you build a much bigger pond right away you will soon enough. This is probably not what you were hoping to hear but I am sure you want the best for your koi...
