Is that all you test for? You don't test pH, Ammonia, Nitrite, Nitrate, Phosphate, Alkalinity, etc?

Your magnesium should be around 1350. Think of Mg as the fulcrum on a teeter totter. You can't keep alkalinity and calcium up if your magnesium is very low. In your case, it is very low. Try to aim for Calcium 400-430, Alk 8-10, Mg 1350-1400. pH should be 8.0-8.4, and Am, nitrite, nitrate, and phos all 0. Not close to zero, but AT zero.
