Robelle 1 qt. Pool Water Brightener and Clarifier (12-Pack)

Robelle Water Brightener and Clarifier, a super concentrated formula, coagulates dirt, oils and other microscopic particles so they can be eliminated from the pool water by the filter. At half the dosage rates of other swimming pool clarifiers this fast-acting product will provide professional results at a competitive price. While Robelle Water Brightener and Clarifier improves the function of sand and cartridge filters, it is not recommended for diatomaceous earth (DE) pool filters. Use this product weekly to enjoy cleaner looking, sparkling clear pool water.
