Cycling a new 75 gal. tank

[Jrquicker at aol_com]

I'm going to set up a75 gal. fresh water tank,and I'm going withco2 
injection, heavy planting, under gravel heating cables. My question is, when 
I plant the tank, start Injecting co2, how long should it be before I add the 
fish? Should I keep an eye on all the parameters? Will the tank start cycling 
with out fish? I'm trying to do every thing right and I am open to any good 
advise that  any one has. Thank You -------Jack
