Can u have to high a calcium level? I have tried to measure mine but the level is to high. I think it should be around 450ppm.
I finally got a good reading on my calcium. It is 540. Is this to high?? I think that i will let it drop off some.
A good calcium level should be anywhere between 380-450.
Check your Alkalinity.
Calcium and Alkalinity are tied to each other.
Think of a balance. One side goes up, the other goes down.
