That's a very good point to test the new saltwater. Its such a trusted saltwater that I didn't think it would mix high. I use the red Sea Pro calcium test kit and it's recently ranked best tester for calcium by BRS so I can't imagine it's the test kit. TBH, my calcium has always measured high since I owned the test kit. So at least it's consistent 😊.

I will test the calcium for the new water next time I do my water change.
