----- the measurement method is based on titration, i.

E.

The reagent is added to the test water sample drop by drop until the colour changes in accordance with the attached colour standard.

The measurement result (concentration of ca2+ and mg2+ ions) is obtained in mg.

L, the value of total hardness is expressed in german degrees.

Composition of the kit: - reagent bottles (3 pcs) - reagent powder containers (2 pcs) - syringe - test tube - manual - pictorial manual including colour standardin plant aquaria, in addition to the total concentration of calcium and magnesium (total hardness), the mutual ratio of the concentrations of these elements is important.

This is because there is sometimes a magnesium deficiency with a normal total hardness.

Magnesium is of fundamental importance for proper plant growth - it is at the centre of the chlorophyll molecule responsible for photosynthesis.

The correct ratio of magnesium to calcium should be approximately 1:5.

With the aquatest ca-mg, the total hardness is also measured with great accuracy over a wide range of values.
