## 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.

Review: I emailed Fritz about some quries and their response was prompt and friendly. been using these for tanks and i do not need to add any salts or whatever. Fzz7 will stink like old eggs and a bit brownish but it is normal, not spoiled. Fritzguard is bluish and dun need it as much as Fzz7. Keep them normally in cabinet and use them every water change. Instructions are clear..
Review: I tried quite a no of other bacteria for my fish tank and found this to be the most effective. Only a small amount is needed for a stabilised tank.

## Questions & Answers

**Q: Would this be good for kickstarting a new aquaponics system?**
A: Yes.   It works excellent.

**Q: So just got my gallon jug in... It has a slight odor to it but its pink in color, not dark or anything...is it still good?**
A: Absolutely. I have used a lot of this stuff, and have received it in slightly brown colors all the ways to the pinkish color, and it always has an earthy odor to it. It always has worked for me.

**Q: Will it work if I put it before adding ammonia to the tank?**
A: Assume you're using the ammonia to cycle/start a new tank? Pure ammonia is not to be added if there will be fish in the tank, only when doing a fish-less cycle; the fish and their waste will supply the ammonia for the bacteria to grow and survive; be sure to keep testing the parameters of the water with a test kit; look up the nitrogen cycle

**Q: Is it supposed to be pink/purple? Thank you.**
A: I havent seen a purple color yet so far. Mine been a light to dark pink color.
