MD Pellets

MD Pellets are a slow-release probiotic pellet designed to directly target the muck layer at the bottom of lakes and ponds.  MD Pellets sink to the bottom and penetrate the muck layer to deliver essential bio-stimulants and select bacterial cultures that speed the breakdown of organic debris and muck.  This pelletized probiotic reduces the available internal nutrient reservoir on the bottom of lakes and ponds to improve water quality and clarity.

The MD Pellets can be applied over the entire water body or to specific areas such as shorelines, beaches, or coves.  They also excel at degrading dead floating vegetation or tussocks when used in conjunction with PondZilla Pro.  For the best results, broadcast the MD Pellets evenly over the targeted area.

NOTE: MD Pellets DO NOT kill aquatic plants or algae

The Science Behind It

Lakes and ponds are catch basins for the many sources of nutrient pollution.  Excess nitrogen and phosphorus from animal or fish waste, stormwater runoff, grass clippings or leaves, and fertilizers from agriculture are a just a few examples of the nutrient pollution that eventually settles at the bottom of lakes and ponds.  Lake and pond bottoms that are overloaded with these nutrients can experience oxygen depletions, fish kills, or harmful algae blooms that negatively impact the water bodies’ recreation and economic uses.

MD Pellets were formulated through years of research on how to enhance the natural digestion of the organic debris and muck that stores nitrogen and phosphorus.  This scientifically tested product works in harmony with natural microbial communities to break down the complex compounds into smaller units and release carbon dioxide, water and energy in the process.

Reducing muck buildup in an aquatic environment can lead to increased capacity, improvements in dissolved oxygen levels, reduced nitrogen and phosphorus compounds, and increased water quality.  MD Pellets restore the balance in the aquatic ecosystems on the bottom of lakes and ponds.  Real science.  Real results.


Part of the process of creating the MD Pellets bacterial formula was looking for the strains that grew the fastest and had the best synergy while degrading the dead leaves and weeds, grass, fish and duck waste, and other detritus that makes up pond muck. This graph depicts a study we completed of the germination rates of different bacteria in pond muck. We use data for like this in the constant process of improving not only our products that degrade muck, but all our products.

“At the bottom of a ravine, surrounded by oak, maple, and other trees is Dead Lake. It was given this name because it looked dead. It was covered with floating organic matter and decaying leaves. Through adding PondZilla Black and MD Pellets, it cleared up in a year. Now they are thinking of changing the lake to Live Lake! We have never been so ecstatic, it’s wonderful!” – Lake Manager, Elmer

“The hydrilla is about 80% gone and the standpipe unplugged itself since I applied a granular herbicide followed by MD pellets. The rest of the hydrilla is brown and looks like it is on the way out. Meanwhile the smell in the pond is slightly altered, not quite so anaerobic, and the water is a little more acidic. The fish are still healthy and shiny and fight like demons. Anyway, I want to thank you so very much for how you have helped me and my pond.” – Greenville, SC


Case Studies



Case 1: Muck Reduction in the field

Vertex MDP pond Md pellet graph verticalA lake management company in the Ft Meyers, Florida area tested the abilities of our MD Pellets to degrade pond muck against another treatment in golf course ponds over two months. In the 60 day period, the muck levels in the pond treated with the competitor’s product increased by 3 inches. A nearby pond was left untreated as a control and lost 5 inches of muck during the study. In the same time, MD Pellets removed a full foot of bottom sludge, or half of the muck in its pond.  To learn more, read here.



Case 2: Wouldn’t it be nice to see the bottom of your lake and eliminate dredging projects?

Aquaculture_Muck_DredgingA fish farmer in Eastern Texas grows his fish stock the natural way, as he prefers to stay away from chemicals and he does not keep extremely high population densities. The biggest concern he has is the amount of muck fish generate and how much room it takes up which is where MD Pellets come in for Bob. MD Pellets are all natural and reduce muck through high concentrations of helpful bacteria and biostimulants, reducing the need to dredge the ponds. It saves thousands of dollars annually and doesn’t have an adverse effect on the fish. Sticking to his methods he is rarely required to feed his fish, and with the lack of a chemical presence he can keep the price of his fish low while they are among the healthiest and fastest growing fish on the market, with trophy largemouth bass being caught seven years after stock date. The fish farm’s inventory consists of channel catfish, blue gills, sunfish, largemouth bass, threadfin shad, fathead minnows and season stock of triploid grass carp, black crappies, and striped bass.


Dosage Rates

  • Traditional Dose: Feed 10-lb to 25-lb per surface-acre once per month depending on depth of muck or extent of surface debris.
  • Super Dose: For ponds or lakes where they would like to degrade up to 1 foot per month. Feed 50# per acre once per month.
  • Temperature Range: Works best when water temperature is 60° F (17°C) to 130°F (54°C). The warmer it is the faster they reproduce and digest sludge.



Lakes: MD Pellets can be distributed into a lake by a fertilizer spreader attached to the back of the boat. MD Pellets are typically 1/10th to 1/20th of the cost of dredging.

Decorative Ponds: MD Pellets are a nice way to keep the pond in check and keep muck to a minimum.

Retention Ponds: Retention ponds start out nice and beautiful and after a few years they become loaded with floating organic matter and muck. MD Pellets are an easy way to help balance them out and reduce muck. These pellets will also work well in retention ponds that may have a lot of road salt. A biologically cleaned pond is a happy pond. A mechanically cleaned pond can often be unhappy for some time as it tries to find biological balance.

Golf Courses: Golf courses can get a lot of muck due to runoff, high nutrient loadings, and leaf and grass waste. MD Pellets are an easy and affordable way to keep golf course ponds free of muck and more importantly to help keep them biologically balanced.

Shorelines: Used by homeowners to reduce muck around the shoreline. Just sprinkle some pellets around a dock once a month and let them sink into the muck. Month by month the lake bottom will clean up. Many customers have called them little vacuum cleaners as they see the muck reduce.

Aquaculture: Used to degrade fish poop that accumulates in the bottom of a pond. MD Pellets have proven to be economical and efficient for fish farmers who want to minimize muck accumulation as an alternative to dredging.

Clarify water and degrade pond muck and sludge in lakes and pondsWith four feet of muck, widgeon grass, alligator weed, and torpedo grass, this Florida pond was the neighborhood eyesore. The applicator used a diquat based aquatic herbicide to kill the aquatic plants and leave the remaining debris. Following herbicide application, PondZilla Black and MD Pellets were used to degrade one foot of muck and recycle dead organics. The applicator was amazed and the residents were ecstatic.

Lake Management - Aquatic Algae - HydrodictyonThis Ohio pond had a hydrodictyon problem and had not looked good in years. With aeration and PondZilla Black blended with an algaecide/herbicide, along with our Summer Slam and MD Pellets, the applicator cleaned up this pond like never before.
