I have a 20 gallon reef tank with two bta's. One is about 2 inchs in diameter and bleached out but I am bring it back- it has regained coloration and is healthy. But my other one is about 3 inchs in diameter and it was all green and healthy when I got it about 2 months ago but it seems to have slowly declined in health. The anemone is ok but this morning it fell down upside on itself which I know isn't good and it's tentacles aren't inflated. All water params are fine, all corals in the tank are fine and the other bta is getting healthier. I was wondering if it needs more light. I have a 65 watt pc fixture. So a little more than 3wpg. I am thinking about getting a 130 watt pc on it. Would that be better for it? Or what should I get? If I get this how would I acclimate the corals to it since it is double the intensity? I can't but them all on the bottom of the tank so they can adjust.
