- Controls growth of algae and submerged weeds by coloring the
water and absorbing sunlight needed for their survival.
- Use only in ornamental waters, recreational waters not intended for
swimming, and in waters not intended for edible fish.
- Helps prevent algae blooms.
Algae Blocker controls the growth of algae, underwater
aquatic weeds, and other undesirable aquatic plant life in ornamental and recreational
closed system ponds (man-made), and in lakes and fountains. Algae Blocker turns the
pond water an attractive blue-green color, which lasts up to four months, thus blocking
out the sunlight which algae and undesirable plant life need to grow.
