This copper-based long life winterize will help prevent the multiplication of most types of algae for up to 3 months during the winter. This product is only suitable for use with chlorine, bromine and salt-treated pools. Will treat up to 12,000 gallons of water.
Test your pool/spa water to establish what the existing chemical level is in your water. For best results, it is recommended that this product is not used until the pool water temperature drops to 10 degrees C. Shock your pool with Granular chlorine shock to achieve a chlorine level of between 5 and 10mg/l. Where possible allow the filtration system to run for at least 8 hours after the application to ensure the product is well distributed throughout the pool.
