The Salifert Carbonate Hardness/Alkalinity Test Kit measures the carbonate and bicarbonate levels in your tank, both of which contribute heavily to the stabilization of an appropriate and healthy pH balance, a level of pH 8.1 - 8.4. In regards to fluctuation, there should be no more than a 5% change from the optimal 2.8 meq/L, with a maximum fluctuation of 0.14 meq/L. The Salifert Carbonate Hardness/Alkalinity Test Kit is incredibly accurate and can detect even the most minor changes in alkalinity level, measuring incrementally by 0.1 meq/L. A sharp change in water color will be present when fluctuations are detected. This test will not impact the sensitive balance of your pH system. Accurate and immediate carbonate hardness and alkalinity testing kit Detects carbonate and bicarbonate found in active aquariums Performs up to 100 accurate tests
