how long does bio spira last?

[papa_bear_21]

so I've been thinking. with bio spira being as good as it is, of keeping some on hand. How long can it be kept, given that it is properly stored? I have the means to store it, and all that, but dont want too stock it if it wont last long...

I don't think it has a long shelf life, but someone correct me if I'm wrong. Bio spira contains all the good bacteria and if not put in a tank with fish producing waste, the bacteria can't eat to survive.

I think it should be good for a few months unopened in the fridge, maybe less if it's opened.

If I remember correctly, an unopened, refrigerated pack has a shelf life of six months.
