Champion Pool Shock - Ready To Use Liquid Chlorine - Commercial Grade 12.5% Concentrated Strength - 1 Gallon

How to use disinfect pool water using Champion Pool Shock 12.5%: For a new pool or for spring start up, superchlorinate with (64 to 128 oz.) on 10% pool shock or (52 to 104 oz.) on 12.5% pool shock for each 10,000 gallons of water to yield 5 to 10 PPM available chlorine by weight. Check the level of available chlorine with a test kit. Adjust and maintain pool water pH to between 7.2 to 7.6 and alkalinity between 50 to 100 PPM. To maintain the pool, make sure your pool pump is running, add manually or by a feeder device (13 oz.) on 10% pool shock or (11 oz.) on 12.5% pool shock for each 10,000 gallons of water to yield an available chlorine residual between 0.6 to 1.0 PPM by weight. Stabilized pools should maintain a residual of 1.0 to 1.5 PPM available chlorine. Test the pH, available chlorine residual and alkalinity of the water frequently with the appropriate test kits. Frequency of water treatment will depend upon temperature and number of swimmers. Every 7 days, or as necessary, superchlorinate the pool. Repeat directions above for new pool and spring start up. Check the level of available chlorine with a test kit. DO NOT enter pool until the chlorine residual drops below 4.0 PPM.
