Test sticks for the semi-quantitative determination of the total hardness (Ca 2+ , Mg 2+ ), carbonate hardness (HCO 3 , CO 3 2 ) and the pH value of aquarium water.Ranges:total hardness 5 25 dcarbonate hardness 3 20 dpH value 6,4 8,4The total hardness of a water is caused by its content of calcium and magnesium salts (Ca 2+ , Mg 2+ ). When measuring the total hardness, the sum of these salts is determined. The carbonate hardness is a part of the total hardness and is caused by that portion of alkaline earth metals which are equivalent to the carbonate and hydrogen carbonate ions (CO 3 2- , HCO 3 - ) the buffer properties of the water. Water with a low carbonate hardness is not sufficiently buffered, therefore the pH value can fluctuate easily. The pH value indicates whether the water is acidic, alkaline or neutral. Water with a pH of 7 is called neutral. Towards lower pH values the water becomes increasingly acidic, towards higher pH values it becomes more alkaline. Instruction Sheet
