i have the same type of lighting system you have in my 180....(your tank is 4 inches higher)....your lighting is fine if you keep your corals half way up the tank towards the top.....keep mushrooms ect on the ground....i have all kinds of corals with no problems...if your corals aren't sitting on the bottom and your still having problems..i would look to your water quality as being hte problem..dont go crazy buying all mh lighting and stuff...you should be fine with what you have....if your water quality is crap, then all the lighting in the world wont help..
