NEED HELP STAT!

ok so I seem to have an issue with receding tissue on LPS corals that I have kept for years successfully. I first started noticing these issues after I lost all my sps as I have unsuccessfully raised sps since installing my bio-pellet reactor I took it offline, cleaned it, and stowed it away.
