I know you can get calcium deposits, if you add excess Ca or add it too quickly, but why would I be getting calcium deposits without adding anything to the tank? I'm using Reef Crystals, and have normal water quality, as far as I can tell. Can someone tell me what might be going on? Could the small, white deposits be something other than Ca? Thanks in advance.
