Brightwell MicroBacter 7 -

Our product is a sophisticated blend of non-pathogenic aerobic and anaerobic microorganisms, along with natural enzymes, meticulously crafted to establish biological filtration in new aquarium setups. It also accelerates processes like nitrification, denitrification, and organic waste degradation in both marine and freshwater aquaria, achieving complete nutrient remineralization. These beneficial microbes are delivered in a state of suspended animation to ensure maximum longevity, and the formulation is the result of extensive research conducted by microbiologists.


  1. Swift reduction of organic carbon, ammonia, nitrite, nitrate, and phosphate levels.
  2. Decomposition of uneaten/undigested food, excreta, detritus, and other latent organic matter, resulting in a cleaner and healthier aquarium substrate.
  3. Conversion of organic compounds into nutrients that promote the growth of photosynthetic organisms.
  4. Significant reduction in hydrogen sulfide production.
  5. Increased concentration of dissolved oxygen.
  6. Limited availability of pre-existing phosphate to undesirable forms of algae and cyanobacteria.
  7. Improved water clarity.

Scientific Background The concentration of dissolved and particulate organic materials in aquatic environments profoundly affects the appearance and health of the ecosystem. Low-nutrient environments are marked by high water clarity, lack of unpleasant odors, and the absence of microalgae and cyanobacteria. Conversely, nutrient-rich aquaria exhibit the opposite characteristics, making them less desirable for maintaining healthy aquarium inhabitants.

Brightwell Aquatics MicrōBacter7 is a meticulously chosen blend of highly effective microbes and enzymes that rapidly reduce the concentrations of organic nitrogen, ammonia, nitrite, nitrate, phosphate, and organic carbon in all marine and freshwater ecosystems. This leads to a significant improvement in water quality, ultimately benefiting the health of aquarium inhabitants. MicrōBacter7 does not require refrigeration, but storing it in a cool, shaded area will prolong its activity and shelf-life.

Instructions and Recommendations

  1. Shake the product well before use.
  2. Mix the appropriate volume of MicrōBacter7 (see below) with 250 ml (~8 fl. oz.) of aquarium water in a clean container before adding it to the aquarium.
  3. When using a pipette to dispense MicrōBacter7 below the water level, ensure thorough cleaning of the pipette with fresh water before returning it to the MicrōBacter7 bottle to prevent contamination.
  4. For the best results, consider adding the mixture to an external biological filtration system (if applicable). Do not add it to pump intake ports.
  5. Use MicrōBacter7 within one year of purchase for optimal effectiveness.
  6. Overdosing MicrōBacter7 will not significantly enhance its effectiveness. Follow the recommendations below for best results.

For Medium- to High-nutrient Systems or to Seed Biological Filtration in New Aquaria:

  • Add 5 ml (1 capful) per 25 US gallons (94.6 L) of aquarium water daily for the first two weeks.
  • Turn off protein skimming and UV sterilization for 4 hours after each addition.
  • Noticeable improvements in water clarity should be observed within 30 minutes.

For Stable, Low-nutrient Systems:

  • Add 5 ml (1 capful) per 50 US gallons (189.3 L) of aquarium water no more than once a week.
  • Alternatively, add 1 drop per 50 US gallons daily (or 1 drop per 25 US gallons every other day).
  • Turn off protein skimming and UV sterilization for 4 hours after each addition.
  • Dosage can be adjusted based on aquarium needs, but do not exceed 1 drop per 10 US gallons daily.
  • Over time, reduce the dosage or frequency by up to 50% to maintain a low-nutrient environment.

During changes in biological filtration or when increasing the aquarium bioload, dose 1 drop per 25 US gallons daily for one week, then resume the "low-nutrient" dosage.

Caution: Keep out of reach of children. Not for human consumption.

Ingredients Purified water, proprietary blend of natural enzymes and non-pathogenic, beneficial microorganisms.
