Has anyone encountered phenomenon of measuring calcium at a value of 500 PPM?
Other values are normal, Mg-1,350, dKh-7.3, salinity 1,025
400L tank, 8 weeks old, with a 20 of SPS without dosing 1,2,3 yet except of manually fixing dKh buffer.

Have you tried testing again, bad test?

I have had Ca above 500 before. Nothing too bad will happen.

Hello I'm Korean.. So I am not accustomed to English..
I'm using for probiotic reef salt.
Me too, without dosing yet.
But why calcium value of 500 PPM? And Mg 1500 PPM ?

I'm curious, too
