Just made the switch to AF from Zeovit and I did my first water change with AF prob biotic salt. I have almost all of the bottles except Pro Bio S. I do have NP pro andBio S not Pro. Can I use the Bio S in substitute of pro bio since I am not going through a new cycle?
Thanks, Larry

Yes Larry,
It is ok, just move over to Pro Bio S when you see nitrates appear, then move over to Pro Bio S and NP Pro for regular routine. Cheers!
