Kasco’s Macro-Zyme Beneficial Bacteria is the perfect choice to control and eliminate sludge and foul odors in tanks, ponds, and lakes.  Macro-Zyme contains a high concentration of facultative anaerobic bacteria that will rapidly reproduce and consume organic material in your pond or lake. Easy to use and releases billions of beneficial bacteria & enzymes that work around the clock to clean, neutralize, and purify. Application is simple — just apply Macro-Zyme in water 55°(F) or warmer and let it go to work. SAFE for HUMANS., PLANTS, and ANIMALS.

This easy to use product is available in several forms:  as quick-dissolving powder in bulk or in water-soluble bags, as six-ounce pucks, or in 6 lb. blocks. The powder is perfect for treating an entire body of water, like your pond. The pucks are designed for easy spot treatments around docks or swimming areas. Both powder and pucks should be applied every 2-3 weeks when water temps are right. Use blocks for on-going time-release treatment lasting up to a month per block. To maximize the performance of this beneficial bacteria, please consider adding a Kasco aeration or circulation product. There are so many different sizes available, please call us to order.
