I'm a newbie to aquarium keeping, and was never really interested until i saw a saltwater aquarium for the first time. Now I'm planning to start a 55 gallon saltwater tank of my own, and i was wondering about what type(s) of filter i should use. Some people say protein skimmers are necessary for a healthy tank but others dont use them at all. So do I need one? What advantages are there to having a protein skimmer? And would a canister filter work just as well? By the way, my tank will be fowlr
for now, but just might add some corals down the road once i'm ready.
