Algae fighting tips from the pool professionals

Lo-Chlor Tropical Algaecide is a combination of the organo copper complex contained in Lo-Chlor Pool Algaecide together with the proven agent, Alkyl Dimethyl Benzyl Ammonium Chloride. Both are very effective anti-algae treatments. Combined they will overcome the most resistant of algae strains.
As the compound suggests this blend contains ammonia.
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.
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.
