AquaForte GH+ 10kg - Increases overall hardness

Increases the total hardness (GH-value magnesium/calcium hardness) of the pond water. Dosage: 25 ml/gr of GH+ is suitable to increase the value of 150 liters of water by 3 to 4 GH (1 litre/kilo per 6000 litres). Depending on this, dissolve the required amount of GH+ in water in a watering can and spread it on the surface of the water. Points of attention: Before using the GH+, it is recommended to also test the PH value of the water. A high PH value can influence the dissolving power of GH+, so that the result of the action of GH+ would only become measurable after a few weeks. However, it is forbidden to add KH+ and GH+ simultaneously to the water. In this case, an interval of 2 weeks must be observed.
