We have a 37 gallon tank and have 130 watts of light using CF they are 50/50 bulbs 10K, actinic, the tank has been set up for about a month. We have about 60 lbs of live rock and 40 lbs of live sand, 4 dams, clarky, coral beauty, royal gramma, green serpent, fire shrimp and a scooter blenny. The tank went through a stage of brown on the rocks and sand and the coraline algae was turning white. Now the rocks are turning a neon green, but on the underside of the rock the coraline is looking good. All the water tests say the water is good. We cut down the light from 12 hrs a day to 3 to 5 hrs. We add B-ionic calcium daily. Is this just part of the natural process or are we doing something wrong?
