Hasa Algi Ban 5lbs 64085
Granular Tri-chlor
TO CONTROL BLACK ALGAE IN SWIMMING POOLS
DIRECTIONS FOR USE:
Where algae appears on bottom of pool:
Adjust the pH of the pool water to 7.2-7.6. Turn off filter and wait until water is calm enough to see spot on bottom. For best results brush black algae spots with a stiff bristle or wire brush prior to treatment. Pour approximately 1 oz. (1/8 cup) HASA ALGI-BAN directly over the spot and allow to settle to the bottom. Use enough HASA ALGI-BAN to completely cover the algae spot. Allow HASA ALGI-BAN to dissolve for a period of 45-60 minutes then brush black algae away. It may be necessary to repeat treatment or to allow more contact time.
Where algae is located on pool walls:
Place 1 oz. (1/8 cup) HASA ALGI-BAN in a cotton cloth. Tie
with string and suspend the bag into the water so that it touches the black algae spot. Allow the HASA
ALGI-BAN bag to remain in place for 45-60 minutes, then remove and brush algae away. In extreme
cases it may be necessary to repeat treatment or allow longer contact time. For spot treatment on
walls and bottom use the prescribed dosage regardless of pool volume in gallons.
Where pool is infested with black algae:
Adjust pH and brush as explained above. Add at least one
pound of HASA ALGI-BAN per 4,000 gallons of pool water and broadcast it over entire pool surface all
at one time. Shut down pump for 24 hours. Follow this treatment with a thorough brushing. If a few
traces of black algae remain, the above process should be repeated, or the treatment for spot black
algae should be followed. In severe cases, where the pool has been neglected for long periods of time,
consult your pool service expert for advice.

Please be advised that certain manufacturers - including Pentair® (with their TradeGrade® products), Jandy®/Fluidra® (with their Trade Series Exclusive™ products), and Hayward® (with their Expert Line® products) - do not honor manufacturer warranties on specific product lines purchased online.
These policies are intentionally enforced by the manufacturers to prevent customers from purchasing the same products at lower prices online.
Warranty coverage for these products is generally only available when purchased in person from an authorized local dealer.
While we strive to take care of our customers by offering the lowest possible prices on brand new, genuine products, we do not provide warranty coverage ourselves, nor can we guarantee that the manufacturer will honor the warranty on products purchased from our online store.
It is the buyer’s responsibility to confirm warranty eligibility directly with the manufacturer before making a purchase.
If you are a local customer, you may be able to purchase these items in-store and obtain manufacturer warranty coverage. However, for many of our customers across the country, paying significantly more locally just to access a manufacturer warranty often doesn’t make financial sense, especially when some local suppliers charge considerably higher prices.
By completing your purchase, you acknowledge and agree that we are not responsible for warranty support or claims denied by the manufacturer due to their online sales restrictions.
