Re: Good OHF/HOF filters to reccomend?
I am using 2 OHF boxes for my high bioload goldfishes, but I got my own pump instead. Each OHF is layered with 3 different filter medium. The top white sponge medium is replaced every 4months or so, but the rest is untouched. You can configure your own filter medium layer. Very very convenient, and super low maintence. Doesn't take up space too. Fishes have lived for years now. OHF is very good for bio-filtration due to the large exposed surface for gas exchange.
If you want to consider this setup, I think it's ok as the the fishes you are choosing are not small enough to be sucked by the pump.
