GH+ 1 liter (± 1kg)

Increases the total hardness (proportion of dissolved calcium and magnesium salts) of your pond water. Recommended dosage of GH+: 25 ml/gr GH+ will increase the GH value of 150 liters water by 3-4 GH (1 ltr/kg per 6000 liter). The required quantity of GH+ should then be dissolved in water in a watering can and poured over the surface of the water.

The required quantity of GH+ should then be dissolved in water in a watering can and poured over the surface of the water. Special notes: It is recommended that you also test the PH value of the water before using GH+. A high PH value may affect the solubility of GH+ so that the beneficial impact of GH+ will only be measurable after a few weeks have elapsed. KH+ and GH+ must not be added to the water at the same time. An interval of two weeks should be observed between adding each of these products separately.
