More product is not automatically better. Measure carefully and follow the product label for your pool size and water condition.

Lo-Chlor helps control algae that float in the water as well as algae that cling to pool surfaces, cracks, and crevices.
Blue-Green Algae
Common free-floating algae that can quickly cloud or discolor water
Mustard Algae
Yellow-brown algae that often clings to walls and shaded surfaces
Black Algae
Stubborn surface growth that can thrive in cracks and porous finishes
