:notsure: right now i have a 95 gallon reef tank with a sump and a sock filter and it is just beautiful, ok so i just bought another 135 gallon that will be set up for fowlr
but now the guys who i bought it from, set up and service my tank say they want to put in bio balls ,is that a good idea? or should i just filter this tank like my reef tank?
