Hi, great site, Ok here is my tank set up 11 months with 55 FOWLR, 40 lbs of rock, 1 jawfish, 2 damsels, 2 true percula clowns, 3 yellow clown gobies, and one fat lawnmower blenny. I currently have a 48″ satellite powercompact with 2 dual actinics and 2 dual daylight 10,000k \6700k. I have heard different things about the actinic lights, do I need them for the live rock, i.e. calcareous algae. If not I would like to switch out the actinic lights for 2 50/50 or just another set of dual daylight bulbs.
