Water hardness products

Water hardness is an essential element to keep an eye on for your garden pond. It is necessary to control the level of GH & KH several times a year if you have a pond with fish and plants. A high level of hardness guarantees the good health of your fish in the event of pollution in the water. It is also a complementary contribution in minerals which will allow plants and fish to develop well.
