Hey there. I hope I can help. I've been in the business for over 20 years.
Your calcium is way too high (450 is where it should be)
So is your magnesium.(1350ppm is where it should be)
Did you test anything else?

Hey reefguy, some basic parameters about your tank might help, as well as your maintenance routine:

Lighting?
Nitrate and Phosphate levels?
Freshwater Top-off solution (are you using RODI, tap water?)
Water flow in the tank?
Skimmer?
Water changes?
