My calcium is around 480. What's too high? Yes, I ordered a queen and blue angel off the webz...like a damn dummy, I did not QT them. The blue angel was a bitch trying to get to eat. Eventually ich came and wiped all my shit. I totally emptied the tank, sump, etc..cleaned with bleach. Put all my LR in straight RO water for several days. Killed off most of my coraline. Refilled the tank, let it cycle, bought new livestock...that you now see. No issues!
