Directions for Use

Initial Treatment

  1. Backwash or chemically clean pool filter. Check pool pH; adjust to 7.2-7.6 if necessary.
  2. Add SoftSwim® B to give a content of 50 ppm (1/2 gallon product/10,000 gallons of pool water).
  3. After 24 hours, check pH and SoftSwim® B concentration with test strips and adjust if necessary.

Routine Maintenance

  1. Every week, check SoftSwim® B concentration and pH.
  2. Maintain SoftSwim®B concentration at about 50 ppm. If concentration falls 10 ppm or more, add a top-up dose. The level should not be allowed to drop below 30 ppm.
    • A maintenance dose of 1 pint per 10,000 gallons will raise the level approximately 10 ppm.
