ClearWater Algaecide is a highly effective way to eliminate algae and prevent pool or hot tub water from becoming unpleasant. Although algae doesn’t do any direct harm to bathers it looks unpleasant and provides an ideal environment for germs and bacteria. If algae forms on or below the water’s surface you simply pour the recommended dose of algae remover into the water. Ideally, the algaecide should be applied where water inlets are situated so that it disperses evenly and effectively throughout the water. The amount of algae treatment used depends on the size of the pool or hot tub and the severity of the situation. As with all chemical products, time should be taken carefully read through instructions and warnings.
