ALGAECIDES

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, causing cloudy, discolored and eventually slimy, smelly water. hth® algaecides provide an effective way to combat algae and prevent future algae from forming, keeping your pool healthy and clean for daily enjoyment.
