Is my calcium ok, or is that a bit low?

I wouldn't consider that "too" high, just a tad over the target range of 400-450ppm. If you're dosing, skip it for a week or so and let the number slowly decrease.

What salt mix are you using?

a widely accepted range for cal is 380-460

I use instant ocean reef crystal, I will do another test tomorrow just to double check...oh yeah I do dose, might leave that along until my calcium is slightly under 460--450...thanks guys.

The biggest disadvantage to calcium over 440 is the rapid calcification of pump parts.
