A few facts from the professionals...

  1. Advise pool owner that product may foam and smell for up to 10 days.
  2. Reduce pH to 7.2 for best results.
  3. Use with Starver® Pool Maintenance for badly infested pools.
  4. Note: High doses of quaternary ammonium compound may combine with free chlorine, resulting in excess levels of combined chlorine. This phenomenon lasts 2 or 3 days.
  5. Addition of Lo-Chlor Aqua-Boost is recommended if condition persists.
  6. When added to a pool running with a salt chlorinator the ammonia occasionally reacts with the gases produced in the salt chlorinator cell causing fine bubbles to form on the surface of the pool.
  7. These bubbles will dissipate as soon as the chlorinator is switched off and usually only last 5-7 days.
