PondXpert GreenStop 9000 UVC 11 Watt

The 11w UVC unit treats pond water by exposing it to strong UV light, which causes microscopic algae to clump together into larger particles. These particles then settle at the pond bottom, are drawn into the pond pump, and trapped within filter sponges. Designed for ponds up to 9000 litres (2000 gallons), this entry-level unit includes an extended 8.5m power cable for flexible installation.
