Important: It is normal for this product to cause pool cloudiness, indicating that phosphates are being removed. The duration of the cloudiness will depend on phosphate levels and pool equipment, and can sometimes last up to 48 hours. While pool water is cloudy, swimming should not occur so plan your treatment accordingly. As needed, apply SeaKlear Chitosan Clarifier at a rate of 2 oz per 5,000 gallons of pool water to help clear cloudy water.
