Yup, probably 60+ frags and 8 colonies of SPS and 5 colonies of LPS in the tank. Plus a bunch of oddball corals.

Are you getting any precipitation of any kind on your pumps? I had a problem on my last tank that involved me constantly testing really low levels of calcium, which in turn led me to up the rate I was dosing. THe problem was actually that I was dosing in the wrong ratios, putting in too much alk. It was driving a precipitation reaction. I only figured out what was going on when my pumps all failed in the same week.
