raising calcium levels

[Yumpto]

i use red sea pro salt and i know it all ready has a high calcium haven't done a water change in 2 weeks my dkh is good at a 8.9 and my salinity is 1.025 but my calcium is a 522 and i checked it after my last water change and it was around 440 is there any thing to look for as to why my calcium would creep that high thanks.

If you haven’t added any calcium supplements I would do the test again to rule out test error.
