I have the same lighting except 2 separate units, one 48" and one 36". That way I have over 5 watts per gallon on my 90 gallon. I need to change the bulbs every 8-9 months for sure. It works well so far but I do not have clams, hard corals or anemones. I noticed that they offer a unit with MH. Very pricy though. Has anyone tried those?
