Does anyone know why my Hammer Coral could be receding. I have checked all the water params and they all seem fine except my alkalinty was low (just got back from a bus. trip). Anyway, I added Alkalinity buffer. My hammer has a bare spot that appears to be growing (open skeleton). What can cause this? Any ideas are greatly appreciated.
Thanks,
Mike
