Ultima Total Control Shock & Algeacide Features
Shock treats & controls all algae, including black, green, and yellow
Shock treats and buffers pH
Improves water clarity by supplementing the chlorine already in the pool
One bottle treats 20,000 Gallons
Granular formulation for simple application
Contains chelated copper to prevent staining
Adjust pool water pH to 7.2 - 7.8 range with a total water alkalinity range of 100 to 150 ppm.
To control pool water algae, distribute 3 pounds over water surface for each 20,000 gallons of pool water. This will raise pool water chlorine residual to 4 ppm for immediate anti-algae shock treatment and add 1 ppm of chelated copper sulfate for extended algae relief.
Keeps the water clear for weeks and gives it a nice bluish color. I bought three bottles of the granules at a very reasonable price. Even though I initially bought it in my city, the store no longer carries it, so I was thrilled to find it here. Thanks !!Mary Beth Peropat Sep 14 2018
