• SpaGuard 2Lb Chlorinating Concentrate

SpaGuard Chlorinating Concentrate 2lb (0.9 kg)

In spas, sanitizers such as chlorine is added to destroy bacteria and algae that thrive in a warm water environment. Chlorinating concentrate can be used in regular doses as a sanitizer or in higher doses as a chlorine shock. Granular chlorine has a more neutral pH and will not affect your water’s pH as much as other forms.

Chlorine can be used with a UV sanitation system equipped on most spas as it will not be affected as greatly as other sanitizers.


  • Fast-acting
  • Quick-dissolving
  • Easy to use
  • Can be used as a sanitizer and a shock
  • Apply directly to water while the pump is running

Initial Startup

  • Make sure your filter is cleaned
  • Adjust your spa water’s alkalinity to the correct range
  • Adjust your spa’s water to between pH 7.2 and 7.6
  • Ensure calcium hardness is in the correct range
  • Check for high phosphates and adjust as needed using Spa Guard Phosphate Remover.
  • Use 1/2 teaspoon of SpaGuard Chlorinating Concentrate per 100 gallons of water
    • Check with a test strip or liquid test kit every 20 minutes and repeat as needed until the water is between 3 to 5 ppm

Routine Maintenance

  • Check with a test strip or liquid test kit periodically and add 1/2 teaspoon per 100 gallons of water. Re-Test the water in 20 minutes and repeat adding chlorine until the water is between 3 to 5 ppm
    • Check your chlorine level frequently to ensure your water stays in the recommended range
    • Always check your chlorine level after a large number of people use the spa as this will greatly reduce the amount of sanitizer remaining in the spa

Shocking (Super Chlorination)

  • Add 1 tablespoon of chlorinating concentrate per 100 gallons of spa water
  • May be used instead of using a non-chlorine shock
    • Shocking with either superchlorination or non-chlorine oxidizer should be done at least once a week.
