Calcium to high?

[Ambush0908]

Hello all,

I recently upgraded my testing methods and was a little surprised at my calcium level. It is at 509. I was wondering if I should be concerned or let it go? I do not do any dosing to increase it. I do have crushed coral in my sump. 45 gal tank. 20 gallon sump.

Calcium 509
DKH 8.7
PH 8.1
magnesium 1400
Nitrate 1.95
Phosphate 0
Salinity 1.026

Let it go; it will be fine and decrease on its own

Agreed. It should decrease on its own as things use it

I agree to allow it to drop on it's own but I'd investagate the reason it is so high if not dosing anything. What is the calc level of a newly mixed batch of salt? It has to be coming from someplace.

Thanks. I just saw this and will check. I just mixed and will give it time to settle. After a 10% water change it came down to 464.
