I have a 60 Gallon Tank, 80-90 pounds of liverock, i plan on making it a coral tank. Prob 2 clowns, and a tang only for fish. 1 or 2 damsels also. My question is, is x2 1300gph power heads overkill? I found a great deal online for 2, cheaper than the 800gph and even the 600ish. It says great for 80-200 gallon tanks. Any advice will be great. Thx in advance.
