Algae can thrive everywhere - living in sunshine, on vegetation, in the air and in the soil. Algae is constantly blown into the pool by winds, dust storms and rain. Your water becomes cloudy, discolored and eventually slimy and smelly. HTH® Algaecides provide an effective way to combat algae and prevent future algae from forming - keeping your pool healthy and clean for daily enjoyment.
