Spec Chem Direct’s new PhosZyme is designed to maintain phosphates below 200 ppb, and digest oil and organics to ensure clean water when pools are closed. It removes the food source for algae so pools are easy to close in the winter and open in the spring. The winterizing dosage is 16 ounces per 10,000 gallons of water.
