Testing error or dosing error. Not sure which, of course, or why. Calcium cannot ever spike on its own.

Salt mix/salt you are using for water changes could also do it over time. You can do a large WC with something like tropic marine pro, red sea blue bucket, fritz OG formula,....

What percentage is your reagents at? It’s a known issue that the readings spike around 30% and lower. Guides fix this issue, there is another ongoing thread about this.
