Fritz Aquatics AFA80210 Fritzzyme 7-Freshwater Nitrifying Ba

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..

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.

Absolutely rubbish, please don’t buy this…buy gloop instead for the live bacteria…these don’t work.

Al parecer este producto es muy bueno y cumple con lo que se describe en la página y en las revisiones que se hacen de él, sin embargo lastimosamente llegó a mi casa con la fecha de caducidad expirada hace un año. Si se vuelve a plublicar, seguro lo compro.

Having trouble starting or completing the nitrogen cycle in your aquarium? Need more beneficial bacteria? Use this product, in a heavy dose. IT WORKS !
