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. Pucks are perfect for spot treatments, such as around docks or swimming areas. For powder or blocks, see our other listings.
If there is a UV Sterilizer in the pond, turn it off for at least 48 hours after application.
Works most effectively with the use of an aeration device (e.g. Kasco™ Aerating Fountains or Aerators).
Effective pH range is 5.5 – 8.5 (Optimum is around 7.5).
Minimum dissolved oxygen level required is 2.0 ppm.
Copper levels must be below 0.05 ppm.
