Unsightly and opaque green water in the pond (rarely in the aquarium) is caused by microscopic floating algae. There are two ways to combat these algae. By using a liquid anti-algae agent, such as JBL AlgoPond Green (Use biocides safely. Always read the label and product information before use. Registered at the Federal Institute for Occupational Safety and Health under BAUA number N-43072) or with the help of a UV-C water clarifier, which can simply be added to the filter circuit of the pond or operated with a small pump.
The UV-C water clarifier JBL PROCRISTAL UV-C Compact plus 18 W can simply be integrated into the supply hose in front of the pond filter. The enclosed connection nozzles for 12-40 mm hoses mean that installation is always possible without any problems. The floating algae are passed by germicidal UV-C radiation in the device and then filtered out by the filter. A clean and simple solution! It is important that the pump size fits the UV-C water clarifier, otherwise the water with the algae will flow past the UV-C radiation too quickly. Each JBL UV-C clarifier has a table showing the pond size and the correct pump size. When the water has cleared, the UV-C can simply be switched off and put back into operation as required. JBL gives a functional guarantee for all technical devices so that you can rely on their effectiveness.
