I prefer not to get so excited about it. What we hope for is to see a few cases that seem to work and to learn from them. We already have years of disappointments where the report is the BB doesn't work, that's the majority tally in my rough estimate just watching the threads.
The science is there such that there should be a reasonable chance of the BBs working and maybe the scientists just need more time to try their things. I'm still quite grateful for all the published work of Tim and the good discussions he's had in the past on various boards but I don't know whether anyone has really figured out how to make the whole picture work. I don't think it's a matter of getting the correct species, I think he's got that part. I think there is just some problem with "establishment" of the bacteria from when it comes out of the bottle to when it is fixed in it's biofilms on the filter media. At least that might be part of where the problem is, I don't know.

Insightful responses, as I was anticipating, waterdrop. You confirmed my suspicions regarding these products. People don't use these products with a fishless cycle to CONFIRM that the bacteria are truly being established in the filter media. All these products are marketed towards the impulse aquarium buyer who walks into a store, buys the tank, substrate, dechlorinator, fish and then wants to make it work, so on the advice of the LFS, buys the product in question and hopes for the best.
I haven't seen anything to convince me that one (or more) of these products can't actually be effective at REDUCING the time of the fishless cycle. I am convinced that the fishless cycle is the best way to ensure success with my aquarium long-term, but I don't like the prospects of a 70 day cycle. If I could shorten it to 3 or 4 weeks, then I would consider that a success. I have yet to see a single fishless cycle log here, or elsewhere, that didn't take at least 4 weeks and usually took MUCH longer, up to 10 weeks or more. So, I am now planning to be a guinea pig for these products and cycling.
I have a science background (but not biology), which is why I was so interested in these additives. After all, if the bacteria that are needed have been identified, AND we KNOW that seeding with mature media works, then surely we have been able to harvest those bacteria and somehow put them on the market for purchase. Your comments on the biofilm are interesting, and it is conceivable that the lack of biofilm in these additives actually could make the time for it to "take" a little longer than the marketing people claim, but still less than starting from scratch.
I guess the next question for me to determine the answer to is WHICH of these products will I try in an effort to cut the duration of the fishless cycle down significantly? Currently I am leaning towards Turbo Start, as it is the ONLY one of the products that still requires refrigeration (granted the shipping costs will be higher, but at least I will have a better sense of whether or not the bacteria are still going to be viable). I could also put a drop of the stuff under the microscope when it arrives in an effort to look for viable bacteria. The next question is dosing. Do I follow the directions on the dosing, or do I double it in an effort to get a better "take"? Do I dose it according to their directions, but do it for consecutive days in an attempt for a better 'take" or do I do it as a single dose, and take my chances? I am leaning towards either a double dose, or a dose every day until either the ammonia drops or the bottle runs out!
The issue with Turbo Start is that it uses Nitrobacter, not Nitrospira as the N-bacs. BUT, if they both do the job... then what's the difference? Could the nitrobacter start and then give way to the nitrospira? OR would the nitrobacter just be the dominant species in this particular tank?
I am still looking for any other anecdotal evidence of success or miserable failures, specifically with fishLESS cycling. Any suggestions on how I could go about setting up this "experiment" are welcomed as well. I am interested in offering something to the wealth of knowledge of this board, and if this is my little contribution, then so be it. If my contribution is to verify the skeptics right, then that is something. If my contribution is to show that they can significantly decrease the cycling time, then so much the better.
