I have a 60 gallon tank with currently 6 fish in it now I have a penn plax cascade 700 I want to add a run dual filters on the aquarium but I want to add the cascade 1000 can I add a second bigger one or do they have to be the same size? New to the two filter idea I would have went bigger from the beginning but it was from my old 35 gallon tank so it was large for that set up I appreciate and advice on the subject.
