I'm coming from the freshwater tank hobby and I'm setting up a 90 gallon tank with live rock and invertebrates (eventually) and fish. I'm trying to decide between a canister filter or a sump. I already have my tank and I cannot drill it. Can anyone out there give me the advantages and disadvantages of each system? One other note, I would like to have all my equipment enter the tank through some sort of tube that I can seal around instead of an open section in the lid for a waterfall style return. Thanks a bunch!
