I have used birospira twice on setting up my QT tanks and IME they do work, BUT I add ammonia then the birospira and the ammonia fell to 0 within 2-3 days both times I used it. THEN I add my fish and usually see a small spike in ammonia when I add the cupramine but a small dose of prime usually takes care of that. Both times I used it I felt it worked and I test daily when i have a fish in qt.
If you really want to find out test it yourself, a small bottle of birospira is just 14 dollars, set up your qt add the ammonia and see how fast it drops to 0. Cheap easy and you're not taking anybodies word for it.
