Macro-Zyme ™ 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 sludge
  • Clear water and help restore a healthy oxygen level

Macro-Zyme ™ is available in easy-to-use water-soluble bags or 25 Lbs. bulk boxes. Just toss the water soluble bags or apply the bulk product at the recommended rates. Macro-Zyme ™ has a shelf life of 2 years! Macro-Zyme ™ contains no dangerous chemicals or harmful bacteria and is safe for wildlife. These bacteria will flourish with the addition of aeration.

Macro-Zyme ™ is available in the following sizes/options with corresponding area treated.

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 watergarden, you will want to turn it off for at least 48 hours after the Macro-Zyme ™ application.

“Macro-Zyme is a terrific product! We began to see amazing results within the first year of use in our 50 year old pond that had 3 feet of muck on its bottom when we began. Now that we are well into our second year, we could not be more pleased. Our pond is beautiful! And, the best part, teh product is so easy to use.” – Tom & Betsy, Charleston, SC

Remember, Macro-Zyme ™ is a blend of Aerobic Bacteria and will work more effectively with the use of an aeration device like the Aerating Fountains or Pond Aerators.
