The town of Oliver owns and operates a 20 km long gravity canal for irrigation and domestic water. The growth of algae in the canal during mid-summer was the cause of numerous complaints from water users. Dramatically within a day after treatment with PX10 almost all algae was gone or dying. No more algae have reappeared since application 8 weeks ago. PX10 is the best product that we have ever used in treating algae growth; it has saved the Town labour costs and has delivered better quality water to users.
