Product Fact Sheet: BioGuard Chem Out

Product Features:

  • Granular neutraliser for chlorine residuals.
  • Will neutralise chlorine residuals, bromine residuals and hydrogen peroxide.
  • Reduces pool down time due to excessive chlorine and bromine residuals or hydrogen peroxide.

Application Instructions:

  1. Test the available chlorine or bromine in the water.
  2. To calculate the ppm of available chlorine that must be removed from the pool, subtract 3 ppm from the free residual of the pool. The resulting number is the amount of free chlorine you must remove before it is safe to swim.
  3. Multiply the result from Step 2 by 180 to get the amount of Chem Out in grams required per 10,000 litres.
  4. Add product directly to the pool scattering around the edge of pool. Do not add through the skimmer.
  5. Keep the pump running throughout.
