Over the past 3 months I've lost 3 corals, 2 brains and 1 lobo, that all started out with a receding flesh line. Also, I just noticed last night that ANOTHER lobo, that I've had for a year, is showing signs of receding flesh. WTF is happening? Params: Cal - 320 DkH - 9 Mag - 1200 SG - 1.025 pH - 8.2 Temp - ~81 Phos & trates - 0 Ive been dosing a 2 part Cal/Alk product every morning and I know the Mag is a LITTLE low. I've been using Tropic Marin Pro Reef for water changes. I have no nuisance pests, haven't noticed any fish nipping at them, etc. The only thing that I can think of would be my lighting. I'm running 92watts over my 29g and had the corals placed on the bottom. At the beginning of the year I changed my bulbs from 2 AquaBlue+, midday, and pure actinic to 2 AquaBlue+ and 2 Pure Actinic bulbs. Except all my other corals are doing GREAT!(Frogspawn, torch, 2 Stylos, softies, etc.). I'm extremely stressed between work and school, then to come home to dead/dying coral is really depressing. I'm thinking about grabbing a midday bulb again to see if it'll help. Maybe the corals werent getting the proper spectrum of lighting?? HELP PLEASE!!?!
