I've got a 30 gallon reef tank with a few LPS corals; hammer, Duncan, toadstool, zoas, GSP, and some clove polyps. We Try to only keep the "easy" corals. Looking for a new LED light as the cheaper Chinese brand I got off Amazon is starting to die after a few months. Wanting something that will last a lot longer. Less than $200 hopefully. tank dimensions 18"deep 20" wide and 20" tall. Any suggestions?
