higher than normal calcium?

[ARGYGANG]

my calcium is at 520 and my alk is at 11 in my nano tank is this to high? all my lps seem fine except my frogspawn its retracted a bit.

Ca 520ppm is high, but it shouldn’t harm corals or fish. Alkalinity of 11 is within limits, but on upper side.

1. what is sg/ salinity?
2. do you dose 2 part?
3. what tests do you use?

Ideally you should lower both parameters( if tests are accurate), but you do not have to go overboard with doing it fast.

IMO, it is fine. 400-550 pm Ca is fine.
