High calcium levels >520 ppm

[themartins]

I was just doing my routine water chemistry testing and have very high calcium. I do not dose anything, just weekly water changes. Will this much calcium cause any problems?

These are the results of all the tests:
Ammonia - 0
Nitrite - 0
Nitrate - 0 (not detectable)
pH - 8.2
Phosphate - 0
Calcium - >520 (actual amount?)
Salinity - 1.027
Kh - 10* dKh

That shouldn't cause any problems. What brand salt do you use? Some are made to have calcium levels that high.

I know I use Oceanic and it has 500+ calcium levels.

I usually use Reef Crystals, but recently had to switch to Kent Reef salt due to local availability.

I just recently quit using Kent Reef, but it wasn't unusual for me to read high 400's/low 500's on the calcium & 1440 mag @ 1.026. Getting into some SPS, I wasn't happy with the Alk level (8.4), and after every pwc, the tank would be milky for a day or two.... Switched to Red Sea Coral Pro and @ 1.026 I'm getting 420/10.5/1340 and the water is crystal clear.
