Update: Yesterday evening I took some water to my lfs (in test tubes) for them to test my calcium & magnesium, he also tested the pH & alk. The results were the same and magnesium was 1350. Ca: 640 pH: 8.0 dkH: 12 Mg: 1350 He said that the high ca is probably since I'm using purple up to kill aiptasia (I didn't think I killed THAT much of it) and that he had an employee there once who's corals started dying, checked the Ca and it was 700, and was not falling out of solution. He was also using purple up to kill aiptasia. I find this odd since people use limewater, kalkwasser, misc calcium stuff to kill their aiptasia all the time. He said check into joes juice because he thinks it works great. I know people use boiling water to kill it too... I'm just surprised that my small diabetic syringe full of purple once every couple weeks to kill 3 or 4 small aiptasias would do this... ????
