What are your magnesium levels?

? does it affect alk if so how?

I don't know, but I know it can affect calcium so I figured I'd throw it out there. Maybe someone else can chime in?

Yeah Mag is probably your problem

What kind of corals do you keep and how heavily stocked is the tank? It sounds like you're alk/cal needs are greater than what you are supplying, got a lot of LPS or any SPS? Or like stated before you're magnisum levels could be out of wack. Or you could have a pH issue.

Here is a good article..

Post the levels you have now. Chances are something is either really low or super high
