Macro-Zyme contains no dangerous chemicals or harmful bacteria and is safe for wildlife. These bacteria will flourish with the addition of aeration. Kasco Marine Macro-Zyme is available in the following sizes/options with corresponding area treated.
Macro-Zyme contains a high concentration of facultative anaerobic bacteria that rapidly reproduce and consume organic muck in your pond. This high concentration of beneficial bacteria will immediately go to work digesting carbons, fats, starches, proteins, and cellulose materials in your pond, cleaning the pond and improving the smells.

It is the perfect choice for the control and elimination of sludge and foul odor in tanks, ponds, and lakes. Once introduced, Macro-Zyme quickly releases billions of friendly and beneficial bacteria and enzymes that work around the clock to clear, neutralize, and purify water.

Used by professionals since 1991, this concentrated professional grade formula was the first on the market to introduce a 1-step maintenance program that utilizes natural bacteria and enzymes to rapidly biodegrade top and bottom sludge while reducing components that contribute to sludge build up in ponds of all sizes. Macro-Zyme will also reduce nitrates and phosphates. These bacteria will:

Reduce odors in 24 hours or less
Rapidly remove dead grass, leaves, paper, fish waste, and organic sludge
Clear water and help restore a healthy oxygen level
Pond treatment with Macro-Zyme is quick and easy. First, you must determine the pond capacity or water volume. To do this, you will need to know the length, width, and depth of the pond. With this info, you can use our Pond Sizing Calculator to determine the total gallons and acre feet of water in your pond and use the proper amount of Macro-Zyme. Once you have determined the total gallons of your pond, follow the label instructions for proper dosage depending on the Macro-Zyme size you have. If there is a UV Sterilizer in your water garden, you will want to turn it off for at least 48 hours after the Macro-Zyme application.
Remember, Kasco Marine Macro-Zyme is a blend of facultative anaerobic bacteria and will work more effectively with the use of an aeration device like Kasco Marine's Aerating Fountains or Aerators.
