I read the manufacturers site... (thanks Hank) and it is pretty

My issues are mostly along the lines of what else is it doing....

the big issue is this...
So it eats all the nasties... what does it do with them?
The law of Conservation of Mass says the nasties have to go
somewhere .. but where do they go? Does the Bacteria simply
continue reproduction until such time as there is nothing left to
feed on then die back (releasing all the nasties for the next
cycle growth)?

The stuff has to go somewhere ... just because you can't see it
does not mean it is gone ... I just can't help but think of a
loaded gun just lying there ready to go off...

I think you should send these questions directly to the manufacturer;
they are the only ones who can truly answer them unless someone here is
a chemist and has done research into the bacteria / enzyme mixture in BZT.
