Regulate the acidity of your pond water!
KH Plus increases the carbonate hardness (KH value) of the pond water quickly and easily. The KH value is expressed in the German degree of hardness (DH). A sufficiently high KH value, between 4° and 8° DH, prevents the acidification of the pond environment and encourages the development of oxygen plants. Contents 250 ml, sufficient for 2,500 litres of water.
