Poolife NST Purify

To use this product, open the entire bag and add the contents. Make sure the pump and filter are running to thoroughly mix the product and ensure good circulation. Our product dissolves quickly and is completely soluble, so there is no need for premixing. Apply it evenly over the surface of the water, with two thirds of the total dose concentrated in the deep end of the pool. For best results, apply when the pool is not in use and wait 15 minutes before swimming, as long as the chlorine concentration is between 1 and 4 ppm. It is important to note that reentry is not permitted above 4 ppm due to potential bodily injury.

For Pools With Moderate Daily Use:

• Add this product weekly at a dose of 1 pound per 10,000 gallons of pool water.
• Each pound of this product will raise the free chlorine concentration by 1 ppm in 10,000 gallons of pool water.
• More frequent and/or heavier doses may be required during periods of heavy use or following heavy rains or high winds.

For Pools Opening and Closing:

• Add this product at a dose of 2 pounds per 10,000 gallons of pool water.
• This dose will provide sufficient oxidizer to eliminate most of the contaminants that accumulate in pool water, and will immediately raise the free chlorine concentration by 2 ppm in 10,000 gallons of pool water.
• Reentry is prohibited above levels of 4 ppm due to risk of bodily injury
