I am new to saltwater tanks. Volunteering at the museum has led me to fix the saltwater tank because I know its in bad shape. I personally own 3 freshwater fish tanks and take EXCELLENT care of my fish. For the next post I will post pictures of the setup including all of the equipment. Now, I need you guys to identify the equipment, tell me what else we need, and tell me how to do water changes on saltwater tanks because I'm assuming that it is a different process than freshwater.
