Well I have a 55 gallon freshwater Oscar tank(2 Oscars that is)right now and I want to transform it into a saltwater tank. I have kept fresh water fish for a few years now and now I finally have a job so that I can buy the stuff that I need with out my parents buying it. I need steps on what I need like filtration, lighting, substrate, etc., what ever else I need. Please help me out. I need to know what I need where I don't screw it up.
