Brightwell Aquatics FlorinBacter Complete Bioculture for All Freshwater and Planted Aquaria, 250 mL


  • Suspension of non-pathogenic aerobic and anaerobic microbes, as well as natural
    enzymes, specifically formulated to establish biological filtration in new aquarium set-ups,
    and to enhance the rate of nitrification, denitrification, and organic waste degradation
    through complete nutrient remineralization. Specifically formulated for use in 
    freshwater aquaria.
  • Particularly useful in freshwater aquaria with high population densities of fish species that
    are active swimmers and/or require frequent feeding.
  • Supplied in a state of suspended animation for maximum longevity.
  • Formulated utilizing extensive data compiled by microbiologists.

Technical Background

The concentration of dissolved and particulate organic materials in any aquatic environment can have a significant impact on the overall appearance of, as well as the health of organisms residing within, that system. Relatively low-nutrient environments are characterized by high water clarity, lack of unpleasant odors, and absence of microalgae and cyanobacteria; this is collectively a result of the lack of nitrogen-, phosphorus-, and carbon-based waste available. Aquaria that are relatively rich in available nutrients have characteristics opposite to the afore mentioned, and are typically not desirable because of the resultant appearance of the system and the difficulty of maintaining healthy aquarium inhabitants.

 Brightwell Aquatics FlorinBacter is a selective complex of extremely effective microbes and enzymes that rapidly reduces the concentrations of organic nitrogen, ammonia, nitrite, nitrate, phosphate, and organic carbon in freshwater ecosystems, leading to greatly improved water quality; better water quality typically leads to healthier aquarium inhabitants. Use of FlorinBacter does not alleviate the requirement for regular partial water changes to help maintain proper concentrations of elements that are vital to long-term health and survival of aquarium inhabitants. No product, regardless of manufacturer's fatuous marketing claims, can do this.

Shake product well before using. Mix appropriate volume of FlorinBacter (see below) with 250-ml (~8 fl. oz.) of aquarium water in a clean container prior to addition to aquarium. If using a pipette to dispense FlorinBacter below water level of container or aquarium, be sure to thoroughly clean pipette with fresh (preferably purified) water prior to placing tube back into FlorinBacter bottle; failure to do so will contaminate the product. Best results may be obtained by adding mixture to external biological filtration system (if applicable). Do not add to pump intake port(s), which can negatively impact the microbes present in FlorinBacter. For best results, use within 1-year of purchase date. Grossly overdosing FlorinBacter will not significantly increase the effectiveness of the product, nor the rate at which it enacts changes in aquaria. The following recommendations are based upon extensive testing and will produce the best results in most aquaria.
