I do not take any offense, in fact I expected this.
I did online research before hand and it seemed that three products seemed to work. BioSpira (which needs refrigeration), Seachem Stability (which does not because the bacteria are in a dormant state) and one other that I forget.
Seachem Stability was the first that I found in a store.
Three aquariums, stocked immediately (with more than a few fish) were cycled after the treatment. I tested with Aquarium Pharmaceuticals drops. I continued testing daily for a week and then a few more times maybe once a week. No ammonia or nitrite, and nitrates are present.
I do understand the scepticism, but this product cycled three tanks for me with no problems.
