    Copper sulfate-fine

    Using to treat multiple ponds - mixing in pump sprayer to treat algae blooms. The fine crystals mix well - that's a plus. I would normally also dry cast in the really bad sections, and for that the fine crystals are too small, almost like dust and catch in air. Dissipate as soon as they touch the water. It reacts quickly, so already seeing results after just a couple of days
