What are some of the side effects of a calcium level of about 520 for about three weeks. i noticed that one of my clowns has what appears to be blimishes in her scales that come from fighting during spawning. i also heard it can cause pumps to malfunction, which also happened. the foam covering the intake(submersible) had become choked after 3 mos operation. THanx in advance.
