cycling my 220g

[sully08]

I just started up a 220 with 100lbs. of macro rock for a base and I added 60 lbs. of well cured live rock, about 8 years old from another tank. after about 18 days I have not seen a ammonia spike, nitrite or nitrate. Is it possible to bypass the cycle if the live rock had a sufficient enough bacteria culture. There was pretty much no die off from the rock. Do you think I could start to add a few fish?
