BioGuard Spot Kill

Spot Kill is a granular dichlor algae killer that kills algae and biofilm in chlorinated or brominated pools. Do not use in biguanide pools. Spot Kill is highly soluble and can be used on any pool surface.

To use Spot Kill:

For Light/Moderate Green Algae:

  1. Perform this procedure at night or when the pool is not in use.
  2. With the pump running, broadcast 125 grams of Spot Kill per 10,000 litres directly into the deep end of the pool. Brush up any undissolved product.  Take particular care in cases where pool surfaces may be bleached.
  3. Wait 12 – 24 hours, then vacuum any remaining algae and clean the filter with Filter Brite.
  4. If algae is still visible after 24 hours, reapply Spot Kill.
  5. Do not swim until the free chlorine residual is 5.0 ppm or less, or the total bromine residual is 8.0 ppm or less.

 

For Extensive Green Algae:

  1. Perform this procedure at night or when the pool is not in use.
  2. With the pump running, at night or when the pool is not in use, broadcast 250 grams of Spot Kill per 10,000 litres directly into the deep end of the pool. Brush up any undissolved product.  Take particular care in cases where pool surfaces may be bleached.
