Pond algae cure will rapidly control green water algae. The specially selected live bacteria in this product multiply & consume the nutrients that cause algae & green water in your pond. While growing & reproducing, these unique strains produce powerful polymers that act as natural flocculants on even the finest algae particles. Algae particles will then be absorbed in your pond filter, sink to the bottom of the pond as well as be consumed by the bacteria present in algae cure. Flocculants are used in water treatment processes to improve the sedimentation or filterability of small or microscopic particles whose removal is difficult or impossible to remove by filtration alone.
