Description
Pond filter combine the mechanical and biological treatment. Microorganisms accumulate to the filter materials which remove the germs and bacteria from the water. By mechanical filtering floating particles and dirt remain in the pond filter by the means of which they no longer return into the pond water.

It takes about 4-6 weeks, until Filter Bacteria have sufficiently colonized the bio pond filter. Only thereafter it is advisable to switch on a UVC Pond Clarifier. Starter bacteria help to shorten the start-up phase of a new filter. Starter bacteria refer to microorganisms especially grown in a laboratory. By adding them, you can shorten the start-up phase considerably. Bacteria are active above a temperature of approximately 10°-12°C, the pond filter´s temperature should exceed 40°C. So the pond filter should be placed in the shadow and not be exposed to direct sunlight.

UVC-pond clarifiers irradiate the water in a flow-through reactor with UV rays. The UV-C radiation destroys the swimming algae. The algae agglutinate to large particles and can be easily removed by means of mechanical filtering. Our UVC clarifiers modify the tertiary and the quaternary structure of the algae proteins by means of UV-radiation. This means the destructions of the algae which can be removed from the water by pond filters.
