sera pond bio balance 

Garden ponds are very strongly exposed to environmental influences such as acid rain. In case of strong sunlight, mineral consumption by the plants is very high. Therefore, reliable stabilization of the water conditions is very important as to maintain the equilibrium within the pond. The carbonate hardness in the pond should be checked regularly with the sera kH-Test. Values between 5 - 10 °dKH are optimal for stabilizing the pH value. sera pond bio balance is very easy to use and to dose. The powder product can be dissolved, e.g. in a watering can, for even distribution on the pond surface. sera pond bio balance is very economic: 550 g increase the hardness in 6000 liters of water by 1 °dGH and 2 °dKH. Due to the practical package sizes of 550 g and 2.5 kg, sera pond bio balance is ideal for every garden pond.
