Brightwell MicroBacter Start XLF 15X creates a nitrifying biological filter in freshwater aquaria of all types and is particularly useful for new startups, resulting in cycling in about 5 to 7 days in most cases. It quickly removes toxic ammonia and nitrite naturally through nitrifying bacterial action. Even though this product is potent, it may be overdosed at up to 5 times rated dosage during aquarium upsets. It should be your first choice to remove ammonia during emergencies where the filter has been inadvertently killed.

Overview

  • Super concentrated 15X Suspension of LIVE non-pathogenic microbes, specifically formulated to extremely rapidly establish biological filtration in new aquarium set-ups, and to enhance the rate of nitrification in existing systems.

  • Useful for rapidly re-establishing nitrification bacteria in case of an emergency.

  • Particularly useful in aquaria with high population densities and when adding new fish.

  • Helpful to re-establish nitrifying bacteria after cleaning rocks and surfaces and after use of medications.
    1. Rapid reduction of ammonia, and nitrite.
    2. Prevents “New Tank Syndrome.”

  • Supplied in a proprietary base which provides for maximum longevity.

  • Formulated utilizing extensive data compiled by microbiologists.

Technical Background

MicroBacter Start XLF 15 X is a highly concentrated, selective complex of live, extremely effective microbes and enzymes that rapidly reduces the concentrations of organic nitrogen, ammonia, and nitrite in freshwater ecosystems, leading to greatly improved water quality and much faster cycling. Use of MicroBacter Start XLF 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.

Shake product well immediately before using. Brightwell recommends that you not use any other type of bacteria product until your cycle with this product is complete. There are no other bacteria species that will be compatible with this nitrifying bacteria product until the cycle is complete! To add other bacteria will significantly lengthen the time it takes to cycle!

Storage: Although product can withstand elevated temperatures for short periods of time, for best longevity and highest potency, keep below 80 deg F and if possible, refrigerate at 50 degrees F. Do not freeze! Freezing can kill the bacteria.

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