Ok, maybe I'm just being impatient - but after my tank treatment, ammonia
just isn't going back to zero. My 10% twice daily water changes are keeping
it at pretty much a constant 1 PPM. I've tried introducing plants and
gravel from cycled tanks, and it's just not getting me very far. Maybe I
just have to be patient, but I'm getting worried that the 1 PPM ammonia is
not going to allow for enough bacteria growth for the tank to cycle again.
Is there any validity to that concern?

Thanks in advance!
