Quartz tubes for UV lamps

Quartz tubes are special glass bulbs. They enclose the UV lamps, otherwise it would lead to a short circuit. In the course of time a lime layer forms on the surface and reduces the effectiveness of the UV lamp. We recommend the Bio Descaler from Koitec Professional, which can also be used to descale pond pumps. Under no circumstances should the tube be cleaned with coarse sponges, as these damage the surface.
