Im building a 20 gal long sump for my 90 gal. LFS owner says to use the bag sock filter with ceramic rings. Ive herd these bags are for saltwater only.
Its a freash water tank and it has really high nitrates cuz its over stocked and i feed all live food. I really want to chose the best design for my sump to get the most cleaning power.
should i go with this sock bag filter or a bio ball set up?
