AquaForte GH+ 10 liter (± 10kg)

Increases the total hardness (proportion of dissolved calcium and magnesium salts) of your pond water.

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. 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.
