HASA Algi-Control Concentrate 72121 is a powerful 32oz algaecide solution specifically formulated to eliminate and prevent yellow and green algae blooms in swimming pools. This concentrated treatment can be applied directly into the pool water or introduced through the circulation system, delivering the best results when directed toward algae-affected areas and along the pool's perimeter. It works well alongside most standard pool maintenance chemicals, though it should be kept away from direct contact with concentrated chlorine or other strong oxidizing agents.
