Well, I have a 1.5" purple w/ green tentacles plate coral. It was doing great until last night. I noticed it is losing flesh. This occured the day after I used Aquavitro's trace chemical. I have to assume this is what caused the problem. I took it out and gave it a Iodine dip and shook the dead flesh off the plate. Params: Ammo: 0 Nitrite: 0 Nitrate: 5 SG: 1.024-5 depending on if the ATO has kicked in yet Ca: 480 pH: 8.4 dKH: 11 Mag: ~1350 Any suggestions?
