Rather than bashing the product that you've used before successfully and just bought repeatedly, why don't you contact Marineland at http://www.marineland.com/support and discuss it with them.
Initially, when it was first introduced, bio-spira was supposed to be refrigerated. That's not a requirement now, although I don't think it's supposed to be exposed to extreme heat or cold. If the product were available from a local distributor it could be controlled better. Where do you live? I may know the sales rep.
Listen, you could also call the 800 operator (1-800-555-1212) and get the 800 number for Marineland customer service. Be cool, describe the problem then ask if there's anything they can do to help. Don't demand and don't whine. You'd be surprised at what customer service reps are willing to do for a customer of their products. If they offer and then send you free products, be sure to thank them by phone or e-mail, then post that they did so here.
