digitata Care.

[OCDP]

Well your first problem is you don't know your calcium or alk. You need to know these paramaters in order to successfully keep SPS. Your lighting may not be completely up to par for it either.

My suggestions... get a calcium test kit ASAP and test your calcium, and adjust it by dosing. Same goes for alkalinity, both are equally important.

Move your digitata up to the highest point in the tank (recieving the most light possible) recieving good overall flow.

I also think you feed quite a bit of liquid foods.. I am sure that must in some way build up in your system. How often do you feed all 3?
