Is 500 calcium too high?

[jayteerq]

My calcium has been stable at 500 since the start of the tank 4 months ago. Highest being 525. My parameters are stable so I always figured it’s okay and it’ll balance out eventually. But if this is too high, how can I reduce it to say 400?

Alk - 9.5
Calcium - 500
Magnesium - 1500

Dosing Kalkwasser to keep alkalinity stable and ph boost.

Its fine. The only risk of high calcium is precipitation. I've had calcium in the 700s without knowing because I use all for reef and rarely test calcium.

It’s fine. I wouldn’t do anything to bring it down.

Thanks guys! What do you mean by precipitation?

Precipitation generally means abiotic deposition of calcium carbonate on sand, rocks, pump impellers and heaters.
