I bought a beatuiful Galaxea coral about 10-11 months ago. It was large and bushy. We switched from 10,000K to 14,000K bulbs shortly after we got the coral. It has been slowly dieing off, and losing color. We just last week, switched back to 10,000K bulbs, but I haven't seen much, if any, improvement. I have tried spot feeding Cyclopeze, but it doesn't seem interested.
