I lost most of my sps a few months back due to hyposalinity and excess kalk problems. Removed what was still alive and decided to use this as a chance to cook my rock. I also bought another skimmer. I cooked the rock for 7 weeks and cleaned the tank real good. A month ago I put the rock back in and slowly reintroduced the surviving SPS plus a few frags. I am slowly losing SPS. They start usually at the base with tissue peeling off. I immediatley remove them when I see this starting. Most of my SPS are also lightening up. From what I have read this is from lack of nutrients (I have started feeding more to try to counteract this) Any ideas on what is wrong?
