Normal range for mixed reef tank

[chris k.]

I have 2 clowns, snails, hermit crabs, gsp, and 2 soft corals not sure what they are. Just wondering what normal calcium, magnesium, and alkalinity should be. Thanx

these are the 2 I forget the name of.

I'd aim for 7-11 dKH, 380-500 ppm calcium, and 1250-1400 ppm magnesium.

These aren't important for your soft corals, but coralline algae will grow well in this range.

My dKH is 7.7. Calcium is 375 and mag is 1200. Thanx for the quick response.

What is the salinity?

It may be low and raising it will boost both calcium and magnesium.

Ammonia nitrite and nitrates are all zero

Quick update did a 25% water change and new parameters are
Dkh 7.0
Mg 1300
Ca 430

Raise it to 35 ppt (1.0264) and the calcium and magnesium levels will be right on target.
