Scuttlebutt on fish forums years ago was that Dr. Tim worked on Biospira and then formed his own company. When I fishless cycled my 300 gallon tank 16 years ago, I dosed very liberally with bacterial additives - as in dumping in a LOT. Just as with filtration in general, "you can't have too much of a good thing.
Patience is the key to fishless cycling. It took my tank about 2 months. The bacteria that consume ammonia colonized quickly. The group of bacteria that consume nitrite took MUCH longer to colonize. It seemed that I had nitrites forever and ever. Once the tank was cycled, I never had another nitrite reading, but did get ammonia readings when I fed my fish UNLIMITED amounts of water melon and after a prolonged power outage.
The biological additives came in handy with the mini-cycle -- I poured (dumped) the bio additive into the tank which quickly took care of the problem. I am a believer in bio additives. I would rather use them rather than seeding the tank with media from some one else's tank and possibly introducing a pathogen to my tank.
