Mitchell - 67 Pond Pucks - 10 LB PAIL

  • Remove excess nutrients (i.e. PO4-, NO3- and NH4+) from the water column
  • Easy to distribute by tossing quick-sinking pucks into a pond
  • Diverse spectrum of microbes able to treat diverse water quality conditions (including facultative and phosphate-removing strains)
  • Reduce BOD, COD and foul odors – including H2S
  • Reduce muck buildup by biodegrading hydrocarbons, lignin and organic pollutants
  • Flexible application rates unlike water-soluble BAGs

Pond Pucks are a natural, biological water treatment formulated to clarify water in ponds, lakes, and small water features while reducing muck buildup. A biodiverse group of beneficial bacteria are incorporated into the pucks to remove excess nutrients from the water column such as phosphates, nitrates and ammonia that can create an unbalanced ecosystem. Ponds containing excess nutrients are often cloudy, unhealthy and susceptible to algal blooms.
Each Pond Puck contains diverse biological elements that work effectively in different water quality conditions, including facultative strains to work in low-oxygen environments.

Active Ingredient: Blend of naturally occurring beneficial aerobic and facultative anaerobic microbes. Contains a minimum of 2.5 x 109 colony forming units/gram.

For use on:

  • Natural ponds
  • Lined ponds
  • Small water features, backyard ponds
  • Lakes

Weeds Controlled

  • Removes excess nutrients from the water column via biological processes (NH4+, NO3- and PO4-).


Directions for Use: Distribute the product evenly over the entire pond or lake surface. Pond Pucks will sink quickly, normally dissolving in several days. Product is most efficient in aerobic environments, but also effective in low oxygen environments through its use of facultative, anaerobic bacteria. Pond aeration is beneficial by promoting proliferation of aerobic bacteria, but not necessary for product efficacy. If an algaecide has been applied, wait a minimum of 14 days before applying Pond Pucks to reestablish the beneficial microbial populations compromised by the algaecide.

Rates are based on the volume of water to be treated and the severity of the problem. Water volume is measured in “acre-feet” (one ACRE-FT = 325,000 GAL of water).
