Algatec's® unique cationic polymeric compound functions as a broad spectrum, non-oxidizing algaecide-microbicide that kills and controls the growth of microorganisms by disturbing their normal metabolic process of the living cell. Algatec® has a powerful synergy with chlorine sanitizers which further enhances algae kill and removal. The product is metal-free, non-hazardous to handle, will not foam, and does not remove chlorine from pool water.
