The Macherey-Nagel Visocolor ECO Calcium Water Test is a colorimetric water test for determining the calcium content of a water sample. Calcium is an important aquatic plant nutrient, which needs to be viewed in correlation with magnesium and potassium. It can be determined in a sufficiently exact way with the calcium test by Macherey-Nagel, which will give you information about possible nutrient deficiencies in your aquatic plants.

Complexometric titration after magnesium salts are precipitated (basis for the reaction in analogy to DIN 38406-3 E3).

  • Sufficient for approx. 100 tests with an average calcium-concentration of 50 mg/l Ca2+
