Thanks for your informative help.
Its just that I got the stuff as a birthday present
(you know you have a good marriage when your wife gives you Bacteria as a
gift!

The whole reason that my tank snowballed into a
Live-Rock project is because I really couldnt
reconcile myself to just dump the stuff in the Aquarium and throw Tangs in
the next day like the LFS dude suggested.
So I have it and dont want it to go to waste. Actually I guess I really do
want it to go to waste

(Lord forgive me for that one)

I would risk the statement that when you cycle the tank
with live rock or live sand than you do not need any
additional bacteria - in form of BioSpira or any other.
Live rock has plenty of bacteria living in the ocean
to populate your tank and do as bilogical filters.
