Let us tell you
How the TopClear Pro works.

Water is pumped into the filter under pressure using a pond pump, a vortex movement forces water through a filter foam pack (mechanical filtration). At the bottom of the filter, there are Bio-Balls which provide biological filtration. Useful bacteria convert harmful substances (ammonia and nitrite) to non-pollutants (nitrate).

The water then flows up past the UV lamp. The UV lamp produces ultraviolet light with a wavelength of exactly 254 nm, at which wavelength the disinfecting capacity is optimal. UV radiation combats floating algae without the use of chemicals and reduces harmful bacteria and germs. The UV-C radiation does not affect the pH value of the pond water and is safe for fish and plants. The UVC device ensures a clear pond within 14 days.

The filtered water flows back into the pond via a hose. The pressure filter has all the connections on the lid and can easily bridge any height differences, allowing it to be placed below the pond water level. The pressure filter can be buried almost completely into the ground or concealed next to the pond.
