Destroys organic waste
1. Use 1 lb. for every 10,000 gallons. Add total required amount at one time. Scatter product directly over pool water surface. Use POWER BLAST only when pool is not in use, as it will produce a temporary high chlorine level. Do not enter pool until the chlorine residual has dropped to a level of 2 ppm.
2. Between applications, maintain required 1.0-3.0 ppm chlorine residual in pool water.
1 lb. pouches
Always mix with only pool water by scattering product over pool surface. If you don't want to close the pool while shock treating, use a non-chlorine shock such as Ultra Quick Swim™ shock oxidizer.
