Calcium levels

[reefkprrn]

When does calcium get to a dangerous level or concerning level. Currently my calcium is 445 ppm using Salifert test kit. The tank is a new tank been up for about 6 weeks. There is no coral in it yet just 200 lbs of live rock. The rock is getting to be a gorgeous purple all over and looks great. I have not dosed any calcium or adding anything to the tank other than Red Sea Coral salt water when water changes are done. What do you guys think? The remaining water parameters are
Salinity 1.023
pH 8.1
Ammonia 0
Nitrites 0
Nitrates 0
calcium 445
alkalinity 10.7 dKh
Not testing Magnesium or phosphates yet.
Thanks

You should boost your salinity to 1.026 as that is what natural sea water is.

Your Alk and Cal are a smidge high, but they are balanced with eachother (I think).

Looks good! Looks like you're ready to go.

Those alkalinity and calcium measurements are fine. This article gives the acceptable ranges for all the parameters:
