[ATTACH]13625.vB[/ATTACH]\n \nHad this for a while now and it shows no growth. Doesn't look dead, but there is some Coraline starting to grow around the edges. Does it need more or less light? Shorter or longer lighting times? Better water? \n \nI know you would like lighting parameters, but I have no idea how to define them. I have a stunner strip (blue and white) and a dual bulb t5 set up. It is about 12" deep and about 15" from the t5s. 20" from the LEDs. It gets about 9 hours a day light time.\n \nWater is Very clean by all standards. 79.4*, 8.2pH, NH3/NH4 0.0, NO2 0.0, NO3- 0.0 and PO3/4 is .25. Minimal CUC and small fish. What else, easy wise, can I add for a coral?
