GLB Algimycin 2000 is comprised of a multi-component blend that controls all types of swimming pool algae including black, green, mustard, and yellow. It is easier to prevent algae growth than to destroy established algae. When this product is used weekly, it prevents algae outbreaks. It has a special wetting agent that penetrates and kills even deeply rooted algae and a unique clarifier and filter aid that removes dead and living algae fast with concentrated coagulants. Algimycin 2000 is compatible with chlorine, bromine, ozone, salt water pools, and biguanide sanitizers.
