A friend of mine is giving me his 125g tank and I have 2 pacus and a pleco in a 50g tank right now.I have a FX5 on the 50g but I need to get a filter for the 125g tank to get it going.Should I get another FX5 to get it cycled and then add the second FX5 to it when I am ready to transplant the fish to the new tank?
