OK, here is the deal. After having a 220 gallon predator tank for about two years I had to break the tank down and replace the stand. So after thinking I would like to make the predator a reef tank. I would like some suggestions on what the differences would be. I have heard that even the sand had to be reaclimated due to its high content of poop or nitrates. Also, I have a set of eight T5's that are hanging over the tank. What would adequate lighting for the tank be? Should I get the tank drilled for a closed loop? I never had a clean up crew in the tank so I know I need to invest in a crew. I have a magnificent foxface, and a sohal tang that I am keeping but would also like to know what wildlife you would add? I had about six maxijet 1200 going on in there but would like to get rid of them and save on some electricity.
