Need help lighting......

[kirkster7]

Hello about 10 months ago I added a CSL BriteLite power compact lighting system to my aquarium, I have right now 2 twin strips of 96 watts each 10,000 k, I wondered is this way too much light for the standard 55 gallon size 13 wide 18 inches deep, it's brighter than all the tanks I have seen with corals, my live rock WAS absolutely beautiful totally covered with corraline algae, now it has some brownish greenish algae on the rocks weekly, if you guys think this is the problem, I think 50/50 lights will be better, let me know, nitrates, nitrites all that is good, I've had no problems with the 4 years I've had the tank until the lights, let me know, Mark

are you saying 4 X 96 PC lights?
That's adequate, definately not on the high end. You should be able to keep many types of corals except for most SPS.
