Algaecide 60 Plus For Algae control in pools
Kills and prevents green, yellow and black algae
Algae, while not harmful to bathers, do not belong in a properly operated swimming pool. If allowed
to grow freely, the pool quickly becomes unusable. Algae can make your pool water cloudy, clog filters, create objectionable odors, increase chlorine demand and reduce effectiveness of other pool chemicals. Using a good algaecide as part of regular pool maintenance is the best way to control these microscopic plants. Algaecide 60 Plus is a highly concentrated liquid algaecide consisting of a cationic polymer, effective in killing different types of algae.
␣ Broad spectrum – Effective on yellow, the greenish free-floating varieties of algae and black algae that cling to the walls and bottoms of pools.
␣ Non-foaming – Unlike the commonly used quaternary ammonium compounds, Algaecide 60 Plus is specially formulated to be non-foaming even when added in high concentration slug doses, thereby enhancing pool appearance.
␣ pH tolerant – Is effective in both acidic and alkaline pH ranges, thereby eliminating the need to alter pool chemistry prior to application.
␣ Non-metallic – This product does not stain pool surfaces or swimmers’ hair.
␣ No chlorine demand – Can be used in pools treated with chlorine chemicals and its use may
reduce the amount of chlorine chemicals normally required.
␣ Compatible with all sanitizers – Is compatible with most chemicals commonly used to treat pools and hence can be used by all.
␣ Preventative & cure – Prevents algae growth, eliminates existing algae in pools and even prevents growth of most algae during the winter months when pools are not in use.
DIRECTIONS FOR USE POOLS
␣ Initial dosage - For pools with just visible algae growth, add 11 to 17 ounces of Algaecide 60 plus per 10,000 gallons of water and remove settled algae. Add 6-11 ounces of this product per 10,000 gallons of water while treating freshly cleaned and filled pools.
␣ Maintenance dosage - Add 2 to 4 fluid ounces per 10,000 gallons of water every 5-7 days after initial treatment for maintenance.
␣ Winterizing - Add 6 to 10 fluid ounces of algaecide per 10,000 gallons of water for pools that have been properly treated during the swim season and are free of visible algae. For pools with some visible algae growth at the end of the swim season, add 12 to 17 ounces per 10,000 gallons of water.
