Green (pond) water, created by millions of floating microscopic floating algae and is a well-known and common problem among pond holders. The water has a green colour which causes the plants and animals in the water to be extracted from, among other things, light and visibility.

A filter pump with UV filtering or an operational loose UV filter causes the algae to be killed and the water becomes crystal clear.

While the water is pumped through the UVCdevice along the Arcadia UVC Lamp, the single-celled algae are exposed to high levels of UVCradiation.
This UVCradiation destroys the algal cells, which are then broken down by bacteria in the filter.

The UVCradiation of the tube lamp decreases over time.
You should therefore periodically replace the tube lamps.
The Arcadia UVC Lamp has a life span of 12 months / one year

Arcadia T5 UVC Lamp performs constantly for a period of 12 months.
A high-quality lamp produced in Europe, which means it is a lamp that lasts longer.
