FlorinBacter ONE Tank Starter BioCulture for Freshwater Planted and Shrimp Aquaria 250ml - Brightwell Aquatics


Item #: BW3360

FlorinBacterOne is designed to jump start the ammonia cycle in freshwater planted and shrimp aquariums to help prevent “New Tank Syndrome.” It removes toxic ammonia and nitrite naturally through bacterial oxidation, instantly creating a biological filter in all freshwater aquaria, which is particularly useful for freshwater shrimp and planted aquariums.

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 FlorinBacterOne is a selective complex of extremely effective microbes and enzymes that rapidly reduces the concentrations of organic nitrogen, ammonia, nitrite, and nitrate in freshwater ecosystems, leading to greatly improved water quality; better water quality typically leads to healthier aquarium inhabitants.

Use of FlorinBacterOne 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. An aquarium is a living ecosystem and requires proper care by the aquarist; regular partial water changes constitute a large part of this care.

  • 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 and denitrification.
  • Specifically formulated for use in shrimp, planted and all freshwater aquaria.
  • Particularly useful in freshwater aquaria with high population densities of shrimp or fish species.
  • Supplied in a state of suspended animation for maximum longevity.
  • Formulated utilizing extensive data compiled by microbiologists.
  • New pump tops allows for easier dosing with one hand.


    • Rapid reduction of ammonia, and nitrite.
    • Prevents “New Tank Syndrome"

    Use Guidelines

    • Important: First, use ShrimpPrep or Brightwell Erase-Cl to completely remove chloramines and chorine from tap water. Chloramine and chlorine are lethal to the bacteria in this product and if not treated will cause it to fail! Do not use old sodium thiosulfate formulas for chlorine removal because they will not remove chloramine.
    • Shake product well before using.
    • Mix appropriate volume of FlorinBacterOne (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 FlorinBacterOne below water level of container or aquarium, be sure to thoroughly clean pipette with fresh (preferably purified) water prior to placing tube back into BacterOne 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 FlorinBacterOne.
    • For best results, use within 1-year of purchase date. 
    • Storage: Although product product does not require refrigeration, and it can withstand storage at room temperature. For best longevity and highest potency, keep refrigerated at 50 degrees F. Do not freeze!
    • Caution: Keep out of reach of children. Not for human consumption.

    System Recommendations

    Bio-Filter Seeding in New Systems:
    • Preferably add 2 ml (1 pump if equipped with a pump, or 2 threads on cap) of FlorinBacterOne per US-gallon of aquarium water.
    • Minimum recommended dosage for new aquariums is 1 ml per US-gallon.
    • Turn UV-sterilization and/or ozonation off for a period of one day following addition to aquaria.
    Ongoing Biological Stability in System:
    • Add 2 ml of FlorinBacterOne per 10 US-gallons of aquarium water per week after initial setup, or switch to FlorinBacter7.
    • This will provide increased water clarity and contribute to the ongoing health and overall vigor of inhabitants.
    • Always add this product during and after treatment of the aquarium with any antibiotic or other medication.
