Hoping i can get some advises in here. I have a 90g tank. 48"x18"Dx28"H. Im currently using single end socket metal halide 2-250w. 2-65 actinic bulbs, but im thinking if i should upgrade to the coralife Aqualight system, the one that comes with 2 HQI MH and 2-96w avctinic. Does anyone have any feedbacks or experiences from this system. If i should upgrade, should i go for the 2-250 HQI or 2-150. Because im having some kinds of heat issue right now, my chiller is pretty loud and its always on, just wonder if i should get the 2-150w to get rid some of these problems. (And i have sps and clams in my tank. will the 2-150w be sufficient to keep them in good health)
