Increases the combined hardness, in a handy bucket
GH Plus is a very effective means to increase the hardness of the pond water. In addition, GH Plus stimulates the growth of oxygen plants and the development of micro-organisms. Good water hardness is necessary for a stable and healthy pond. At a combined hardness (GH) of at least 6° DH, oxygen plants and micro-organisms can occur develop well. A good GH value prevents acidification of the pond. Rainwater in particular lowers the GH value and promotes acidification. Regular checking of the water hardness is therefore desirable. GH Plus increases the hardness of the pond water, without any problem. It works quickly and does not cloud the water.
