Before fighting algae, sludge or excessively high nutrients, the water parameters need to be stable. Stable pH and kH parameters are important for all living organisms in the pond. Too high, too low or fluctuating values can impair or even damage the fragile ecosystem. The OASE WATER TECHNOLOGY products for stabilizing water not only adjust the pH and kH levels, they also help to buffer them. Thus making it unnecessary to treat them too often. Biological equilibrium can be achieved this way.
