Flocculants are used with advantage when the water is cloudy. Flocculant is a clarifying agent that constricts the small particles in the water to the flocks, which sink to the bottom or stick to the sand filter. Flocculant is available as both liquid and tablets.
Flocculant in liquid form is poured directly into the pool. Tablets (bag) is placed in the skimmer. Should the water still be cloudy after that, it is because of the organic pollutants. Use calcium chlorine / shock chlorine granules to shock chlorinate.
Backwash the sand filter 24 hours after flocculation.
