This heat-activated algaecide works best in warmer waters. The Rx Clear® Swimming Pool Algaecide 50 Plus coats your pool walls, keeping algae in suspension.
The formula's surfactant splits algae cells open, effectively killing them. This algaecide allows you to swim immediately after treatment. To avoid foaming, do not exceed recommended dosages. Add to pool near your return to allow for better dispersion into your pool water.
