Maybe someone can help me out here.... I've seen a ton of folks talking about how Prime "kills" the bacteria from the TSS. If this is true, then why does Prime do such a great job in a cycled tank? If the converted ammonia is still available to the biological filter in the form of ammonium in a cycled tank, and the bacteria in TSS is supposedly the same as if the bacteria were left to develop in a normal cycle, why should it be an issue? Sounds pretty suspect to me, and a great way for Tetra to get you to use Aquasafe as your dechlorinator.
