Visible Algae Growth:
Apply 12 ounces of this product per 10,000 gallons of pool water. Settled algae debris may be removed by vacuuming.
Heavy Algae Growth:
First vacuum, clean, and scrub walls. Apply 12 ounces of Black Algaetrine algaecide per 10,000 gallons of pool water. Vacuum to remove algae debris.
(Free of visible algae) Apply 6 ounces of Black Algaetrine algaecide per 10,000 gallons of pool water every 5 to 7 days. NOTE: If high temperatures prevail or pool has unusually heavy use, add maintenance dose more frequently.
Algaecides are most effective when applied in the morning on warm, sunny days. Because black algae is protected by a tough, waxy coat, it is important to use an algaecide specifically for black algae such as Black Algaetrine™ algaecide.
