DIRECTIONS FOR USE
It is a violation of Federal law to use this product in a
manner inconsistent with its label.
When used as directed, this product will kill and prevent
development of Chlorella pyrenoidosa (green algae),
Phorimidium inundatum (black algae), Phorimidium retzii
(Square D Algae), Lyngba versicolor (blue-green algae) and
other swimming pool algae. It is compatible with most
commonly used swimming pool chemicals, but should not
be mixed with soap or other water-treating chemicals. It
works best when added by itself directly to pool water.
FOR USE IN SWIMMING POOLS: Initial Dose: 1 gallon to
50,000 gallons of pool water. Initial dose is used when filling
pool at beginning of the swimming season. If pool has
visible algae growth, treat with initial dose. Vacuum pool
after 24 hours to remove algae debris. If visible algae are
still present or re-appear, repeat treatment procedure as
necessary. When pool is free of visible algae, use
recommended maintenance dose.
Maintenance Dose: 1 quart to 50,000 gallons of pool water.
Maintenance dose should be added at 3 – 5 day intervals. If
high temperatures prevail or pool has heavy use, add
maintenance dose more frequently. If make-up water is added
at the rate of more than 10% per week of pool capacity, add 1
quart for each 10,000 gallons of fresh make-up water added
per week. When swimming season is over, add 1 gallon to
50,000 gallons to treat water left in the pool. This dose helps
provide a measure of control of algae growth during the
winter months. This treatment also helps servicing of pool
before it is returned to use the following season.
FOR USE IN SPAS / WHIRLPOOLS / HOT TUB BATHS: Initial
Dose: Add 12.8 ounces per 5,000 gallons of water. Initial
dose is used when filling of spa/whirlpool/hot tub baths.
Maintenance Dose: Add 3.2 ounces per 5,000 gallons of
water. Maintenance dose should be added at 3 – 5 day
intervals. If high temperatures prevail or spa/whirlpool/hot tub
bath has unusually heavy use, add maintenance dose more
frequently. Drain and clean spa/whirlpool/hot tub bath at least
once a month or as needed depending on bather load.
FOR USE AS A POOL-SIDE SURFACE GERMICIDE: After
cleaning surfaces, use 1 ounce to 4 gallons of water for
sanitizing, or 1 ounce to 2 gallons of water for disinfecting.
Thoroughly wet all treated surfaces. At these dilutions, this
product will also deodorize surfaces efficiently.
