Question on calcium

[Rafty]

Hi all

My calcium has suddenly increased to 520 possibly due to increase output from my reactor and not reducing dosing from pump. I have turned doser off for now to allow it to drift down slowly. Next water change only due in 1 week. Is there a calcium level that is toxic to my tank that I should bring this forward or not? My magnesium is 1300 and DKH 10.1.

Thanks

Reef, I assume?

Ca and alk are both high, but not dangerous at all. Nothing to worry about as long as corals look okay.
