Used by professionals since 1991, Kasco® Macro-Zyme™ Beneficial Bacteria was one of the original water treatments that utilize natural bacteria and enzymes to control and eliminate sludge and foul odors in tanks, ponds and lakes. When introduced into the water, Macro-Zyme™ quickly releases billions of of facultative anaerobic bacteria (beneficial bacteria) & enzymes that work around the clock to clean, neutralize and purify your pond by consuming organic material in your pond or lake. Powder is perfect for treating an entire body of water. For pucks or blocks, see our other listings.
