Either that or they are just trying to avoid scaring customers and store owners into thinking this stuff is too fragile to bother keeping . If it doesn't need it, then why won't they allow stores to stock it unless they buy a special bio-spira fridge?? They could sell it on the shelf with expiration dates like these other bogus products( stability , etc.). 6 months is plenty of shelf-life. More stores would be able to carry it, and they'd make LOTS more money.
Who knows. I'm not arguing, you're right it might be ok.... all I know is I wouldnt trust it to cycle a new tank stocked with fish unless it was fresh and refridgerated.
and that wager still stands to anyone else that wants to take it :joke:
