Hi everyone.I sold my 20 g tank and today I just got a new tank and I'm planing to get a few Ocellaris Clowns , but the problem is.. i never had a saltwater tank. This what i have. 35g aquarium, water filter, double air pump, LED lamp, heater. Do I need something else ? I also have a few questions about saltwater. I heard petstores sale packages to make a saltwater is that true? So if anybody would provide me with more info like step by step I would be Veryyy veryyy apresiative! Thanks for looking =)
