‘We purchased multiple USAF™ units to keep a pond of 8.000m2 free from algae and biofilm. The installation was indeed as promised very simple. The algae and biofilm were gone within 3-6 weeks. We were so happy with these units that we just purchased more units to keep our other pond of 10.000m2 free from algae and biofilm. Delivery and service are just fine.’
