This is the second time I have had this problem when purchasing aquacultered corals. It seems they do just fine for about 4-6 weeks then from the base up slowly start bleaching or losing tissue. They seem to have good polyp extension until eventually the tissue falls off. I always start them out on the bottom of the tank and about the 3rd week move them up about 8-12 inches higher. It is only happening with aquacultured, I believe from Bali. The rest of my tank was started as frags from LFS and fellow reefers that have been growing well with great color and good polyp extension. My tanks is about 24 inches deep (55gallon Hex) with 250watt 14K HQI pendent, light is about 10 inches from the water surface. and a 24 watt pc for blue suppl. The corals dont lose color at all until bleaching appears. It takes a small colony about another to weeks to become fully bleached ounce I notice it starting to bleach from the bottom up. I am stumped is my lighting not intence enough, should I not take so long to move them up higher, am I not meeting their food requirments, it just seems funny I have so far had no problems with any other coral's but these. Any advise, or help. >
