i'm looking to upgrade my lighting. my tank is a 4'x2'x2' 120G. i have mostly softies, a few LPS, and SPS. i'm not really looking to get into alot of SPS, i just want better health, and growth for what i have. would also like to add a RBTA, and clam. do you guys(and girls) think 2x150W DE's with4x21W T-5's for actinic would be adequate. i'm on a limited budget(arent we all?), and am concerned about heat, and energy consumption also.
