Hi, I am currently reviving my an old 4ft overhead filter and wondering what could be the best filter media for it. Thanks in advance
I'd think poret foam would be the lightest with the most surface area. how is this setup? what kind of filtration are you looking to do?
I would choose ANS Mini Bacteria House and biohomme red n grey.
Biohome plus for your powerhead. and the new version of Biohome Ultra for any OHF if you can get it ?, its like Bacteria house in size but far more porous and in the UK its cheaper..
