Was looking for some thoughts concerning coloration. I have been keeping this reef tank for some time now (Almost 2 years). Some of my SPS are growing great and have great coloration. However there are a few SPS corals that have expelled the green color over time (1 year) and kept its reds and blue tips. I know there are probably 50 different possible senerios (Lighting, Feeding, minerals etc..) but was curious to see what some of the thoughts are. I just find it strange that different corals do great and keep the green but there are a few that I cant seem to bring them back. (E.g. Red planet) I also noticed that the ones that have lost the green are the ones that tend to have slow or no growth. I do have a very low nutrient system and going to take the great leap of removing my carbon and GFO since I do have a good size refugium. Will have see what happens. Anyways looking for some other thoughts.
