Liquid Chlorine Pool Shock - Commercial Grade 12.5% Concentrated Strength - 1 Gallon

Product Information

To be sure, check the instructions for the amount needed to produce a 1 ppm change in chlorine levels. In addition to using tablets, you should also sanitize your pool with a liquid or granular chlorine shock treatment every 1 to 2 weeks. If you’re treating an indoor pool, make sure there’s adequate ventilation before opening a chemical container. If necessary, your product’s instructions will direct you to add an acidic pool water amendment to counteract the shock treatment’s high pH. For instance, suppose you have a 33,760 gallons (127,800 L) pool, your current chlorine level is around 0 ppm, and your product directs you to add 1 tablet per 5,000 gallons (19,000 L) to increase chlorine levels by 1 ppm.

Simple floaters are inexpensive, while skimmers that clean debris and dispense chemicals can cost hundreds of dollars (U. Be sure to wear protective gear when diluting or applying chlorine shock treatments and any other pool chemicals. For a quick estimate, measure your pool’s length and width, find the average depth, then multiply length by width by the average depth.Instead, it’s best to use a floating chlorine feeder, chlorinating skimmer, or other automatic dispensing device. Free available chlorine is active and kills germs, while combined chlorine is the amount that’s been used up killing germs. Test your pool water daily if it gets regular use, and maintain a free available chlorine level between 1 and 3 ppm.

To chlorinate a pool, first you’ll need to calculate the volume of the pool if you don’t already know it.Shock treatments bring free available chlorine levels to 8 to 10 ppm, which is outside of the safe range for swimming. The instructions will let you know how much to use to raise levels by 1 ppm per 10,000 gallons (38,000 L) of water.
