Concentrated Live Nitrifying Bacteria

  • Allows Safe Immediate Introduction of Livestock

  • A Safe, Natural Approach to Water Treatment

FritzZyme® TurboStart 700 & 900 contains the most concentrated mix available of proven, effective Live Nitrifying Bacteria.

Nitrifying bacteria can take weeks to naturally establish colonies in new aquariums while ammonia and nitrite can reach lethal levels in only a few days. TurboStart provides the proper balance of bacteria proven to rapidly seed biofilters, greatly reducing the natural cycle time allowing for safe, immediate addition of livestock.

Depending on livestock loads, TurboStart can completely cycle aquariums in as little as 24 hours.

FritzZyme TurboStart may be added to new tanks or established systems any time the biofilter needs fortification including; after water changes, aggressive cleaning, adding new livestock, medicating, or changing filter media.

Fritz Industries was the first company to pioneer commercial-scale cultivation of nitrifying bacteria, and has remained one of only a few in the world with continuous production for over 30 years. In addition to aquarium hobbyists, TurboStart is also used by public aquariums, zoos and professional aquaculture.

TurboStart 700 contains live Nitrosomonas and Nitrobacter freshwater specific species of nitrifying bacteria and TurboStart 900 contains live Nitrosoccocus and Nitrococcus saltwater specific species of nitrifying bacteria.

Using FritzZyme TurboStart 700 & 900
