Pool Line test kit for water hardness (HI38904)
Hardness or TH indicates the total concentration of calcium and magnesium salts: 1 °fH/0.562 °dH hardness corresponds to 10 mg/l (ppm) of calcium carbonate. The harder the water, the greater the risk of deposits of calcium and magnesium salts on pool or pond walls. On the other hand, too soft water is aggressive and corrosive.
The ideal TH for pool water is between 10 and 20 °fH or 5 and 11 °dH.
