Biodyne Environoc 301 Microbes


SKU: N/A Category:


Biodyne Environoc 301 Microbes, an organically certified Biological additive:

Used in aquaponics / biofilters.

Over 23 strains of fresh, viable and natural microbes selected for their capabilities to handle the degradation of “common” organics in wastewater and the reduction of grease and hydrogen sulfide odours. Utilized for wastewater treatment / grease reduction, pond muck reduction and water clarity enhancement.

High count microbial inoculant with efficacy across a number of environmental applications.

By improving biological diversity, you can expect the following benefits:

  • Improved water conditions by reducing harmful levels of Ammonia, Nitrite, Nitrate.
  • Pathogen inhibition as Biodyne’s billions of beneficial microbes out-compete pathogens for food and nutrition.
  • Reduction in nutrient concentration – this means less opportunity for algae proliferation.
  • Reductions in TDS (Total dissolved solids)
  • Reductions in TSS (Total suspended solids)

Additional benefits of Biodyne Environoc 301 Microbes: Colonization of biofilter media – this is where dissolved toxic compounds will be converted into less harmful material.

Dosage: 5ml per 1 cubic meter (1000 liter) of water. Repeat once weekly or with water changes.

The Nitrogen cycle in aquaponics:

Protein is built from amino acids, which are themselves built from nitrogen. All plants and animals contain proteins, and when they die, other organisms consume them and scavenge these proteins for energy. Thus, nitrogen enters the body in the form of proteinous food.

Nitrogen occurs in aquaponic systems as it enters in the form of fish feed. The fish consume the food and the microbes in their bellies break the proteins down to ammonia and ammonium.

Depending on the pH of your water, ammonium may stay ammonium or turn into ammonia, which can be very dangerous. Ammonia has no charge, so the fish have difficulty keeping it out of their bodies. When this happens, the fish are poisoned.

Once ammonia is in the solution, it must be transformed or it will eventually kill the fish. There are two ways to do this: alter your pH to favor ammonium (which is not suggested) or convert the ammonia into nitrates. The series of transformations from an organic form (ammonia) to a plant-available form (nitrate)—and the next step in the cycle—is called nitrification (turning ammonia into nitrite, and turning nitrite into nitrate.)


In almost all environments (except anaerobic environments) ammonia is quickly transformed into nitrite (NO2-). Microbes—or nitrifying bacteria—in the soil or solution add oxygen to (or oxidize) the ammonia. While this is happening, the microbes get the energy to fix carbon (break carbon off of carbon dioxide to build cells). In addition, hydrogen ions (H+) are produced—the very ions that are measured in the pH test and cause water to become acidic.

This process has traditionally been attributed to a bacterium called Nitrosomonas. Recent research shows that there are many hundreds, if not thousands of different species in addition to Nitrosomonas that also do this work.


The next step in the cycle is to convert that nitrite into nitrate. Nitrite is also quite toxic so you never want too much in your system. Fortunately, it represents a lot of stored energy to other [nitrifying] bacteria. These bacteria oxidize the nitrite and use the energy from the process to fix more carbon. Sounds familiar, except this time the result is nitrate (NO3-). Nitrate is a relatively non-toxic form of nitrogen that plants can take up and use to build cells.

The bacterium that has been most commonly recognized for performing this chemical reaction is called Nitrobacter. Again, however, research indicates that there are many bacteria that participate in this reaction besides Nitrobacter.
