## Overview

FritzZyme 7 delivers live, freshwater-specific nitrifying bacteria that rapidly reduce toxic ammonia and nitrite levels, accelerating aquarium cycling and stabilizing biofilters.

## Description

Product Description FritzZyme 7 contains specific strains of live nitrifying bacteria proven to reduce fish loss due to toxic levels of ammonia and nitrite. 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. FritzZyme 7 provides the proper balance of bacteria proven to rapidly seed biofilters, greatly reducing the natural cycle time allowing for safe, immediate addition of livestock. 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. FritzZyme 7 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. FritzZyme 7 contains live freshwater-specific species of nitrifying bacteria. Directions Shake the bottle well before use. Add the recommended dosage to the aquarium water.

Review: Beat on the market to instantly cycle tanks - Brilliant
Review: Absolutely Rubbish! - Absolutely rubbish, please don’t buy this…buy gloop instead for the live bacteria…these don’t work.

*by M***O on 29 June 2015*

Can't report any favourable change to the cycling of my 120 litre greenhouse aquaponics set-up. May have been due to shipping. Are the bottles exposed to extremes of heat during transport that could destroy the bug population in the soup?
