ProTeam from Haviland in Grand Rapids, Michigan, is pleased offer “Severest Algae” –a new, unique copper blend algaecide that kills all algae of any color and any type. This product’s performance actually increases as the temperature in and around the pool water increases, working harder as the sun shines directly on the water. Designed to be used during the summer months, bathers can swim immediately after application. This product is triple chelated to prevent staining on pool surfaces and continuously destroys algae for days after application. Works in both chlorine and bromine sanitized pools. Made in USA.
