## Overview

FritzZyme 9 is an 8-ounce liquid solution containing live nitrifying bacteria specifically designed for saltwater aquariums.

## Description

Product Description               FritzZyme 9 contains saltwater-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 9 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 9 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 9 contains live saltwater-specific species of nitrifying bacteria.                  Directions               For a new system, dose 4 oz (119 ml / ½ cup) per 5 US gallons (19 L). For established systems, use 2 oz (60 ml / ¼ cup) per 5 US gallons (19 L).

## Questions & Answers

**Q: Does it need to be kept in the fridge?  Is it shipped with ice packs?**
A: This item does not need to be refrigerated and is not shipped with ice packs. It can be stored at room temperature.

**Q: Is this the same as their Turbo Start by a different name?**
A: It is a less concentrated solution of the same bacteria, if I recall correctly.  Turbo start should be added all at once, rather than as needed over time. Turbo start also has to be kept cold, and I'm not sure Amazon will ship it that way. I like the flexibility of Fritz 9, so that is what I use.

**Q: can i dump the whole bottle into 90 gal saltwater tank?**
A: it's probably best to follow the dosage instructions !!!  they allow fo multiple dosings over several days

**Q: Son just got a fiddler crab, we need brackish water , will this work?**
A: I don't know everything about brackish water, but I wouldn't think so. I thought brackish water was half salt/half fresh water. I would think you would need sea salt for that.
