What are you using to test your parameters? Are you mixing your own saltwater or purchasing from a fish store? Calcium being that high isn’t too alarming and should go down on its own if you’re not dosing and have corals in your tank to consume it. Your alkalinity is kind of alarming though. I would test your calcium and alkalinity in the tank and in the water you use for water changes to be sure there wasn’t a user error. Certain test kits can’t be very inaccurate and easy to mess up. If it still comes back abnormal for both, you can try a dosing supplement for alkalinity. If you do, be sure to dose slowly and test often to get your level back to normal. Big swings in alkalinity could be very harmful to your reef.

Your alkalinity should be at 7-8, don’t dose it all in one jump slowly get it to that 7-8 mark. Calcium is pretty high don’t dose it if you are… or use a buffer to bring it down don’t bring it all the way down either dose slowly till you get to the 450-500 mark at least.

Salinity also should be 1.026 that’s what I have on my tank
