Am I on the Right Path

High Cal sitting around 520 for almost two weeks. But how I got here will help better understanding let me start from the beginning so in AUG my AC went out tank got almost to 90 degrees. Huge massive bleaching event lost all my SPS in my 265 gallon SPS dominant tank. with a 90 gallon LPS/Softy plumbed into it. Lost a good number of corals in it, but not all. I was running a Calcium reactor on it. Me not thinking I started to get more corals from friends and LFS but did not noticed my PH was extremely low like 5.9 at night. And my Alk was 6.3 Everyone telling me to get Kalk washer it will raise PH, & ALK. So I did but I wasn’t getting my ph in a safe zone then I remember the affluent from the reactor lowers Ph so I shut her off and started running 2part but only ALK & Mag to get them back in range and it worked ph is now 8.1 lowes at night and Alk as of today 8.5 but my Cal is still high. I stop using Kalk washer yesterday in my ATO. I do water changes every Sunday 20-30 %. Am I headed down the right path or am I missing something els todo? To get all my ranges back in normal range.

I wouldn't worry about the calcium being slightly elevated. I'd be more concerned about the 5.9 pH and 6.3ppm alkalinity drops... It sounds like you have the parameters in-check again, though - so I'd just continue with your regular water changes and let it slowly adjust over time.
