I currently have a 55g reef tank. I'm am starting to look at upgrading to be able to house more and bigger fish. I would like to have atleast a 125g tank and have it pre-drilled so I can make my 55g the sump. My question is does adding a sump take place of a filter? If I made the sump would it still be best to have a canister filter/power filter?
Thanks
