I'm thinking I need to expand my lighting on my AP 24. The Par 30 just isn't enough light to cut it on a tank of this size, so I'm looking into going back to fluorescent. Question is, should I do a 2 bulb or 4 bulb t5 unit on a tank that will just be growing Montipora and Chalices? My main fear is that 2 bulb won't give enough coverage for the depth of the tank, but 4 bulb would burn any of the coral I have in there and bleach them. Opinions?
