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.
The addition of Lo-Chlor Aqua-Boostis recommended if the condition persists.
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. These bubbles will dissipate as soon as the chlorinator is switched off and usually only last 5-7 days.
