    Does the job

    I have an inground pool with approximately 17,000 gallons of water. One of these sprinkled even ly over the surface at night, let it stand until the pump goes on the next day, and within 24 hours you see the difference. Works great!

    I've had a 35k pool for 21 years and this stuff is the best. My local pool guy gets $22.50. Pool Supply Mall has the best price even with S&H.
