Algae are microscopic plant life that can multiply rapidly in your swimming pool water in the right conditions. Recovering an algae infested
pool can be time consuming and expensive which is why prevention is always preferable to cure. Our range of algaecides have been specially formulated to help you achieve sparkling clear and algae free water. We offer a choice of weekly dosed and long life algaecides depending on your particular needs. In addition to using a recommended algaecide to support the sanitiser, we would recommend you also take account of the following algae prevention tips (1) Maintain the correct water balance (2) Oxidise your swimming pool water regularly (3) Maintain a consistent sanitiser (chlorine or bromine) level (4) Brush pool walls and vacuum pool floor regularly (5) Ensure filtration and circulation are operating efficiently. Blue Horizons Algae Controller is one of the most popular products for algae prevention. This copper-free algaecide is dosed weekly ensuring your pool is free of many types of algae. Available in 2 litre containers
