A very affordable 40% concentrated alkyl algaecide that will quickly kill yellow and green algae on walls and surfaces. Not recommended for prolonged use due to chlorine depletion. Does cause foaming. Sold in 32 oz (one quart) size, equivalent to one gallon of 10% alkyl often sold in retail stores. May be substituted for a brand of equal or better concentration.
