My tank has been up since June. Nothing in it really but a pair of clowns and a clean-up crew.I have never kept a reef only fish with live rock,maybe a few zoa,mushrooms,hammer, Xenia, and GSP from time to time.Its a 20 long with a 10 gallon sump,lights are 4X CF bulbs.2X55 and 2X65.Water is fine.Can I pull it off?
