New Tank Question

[Shifty203]

Hi there,
So I decided my little 30 gallon tank wasn't big enough to get any fish I really wanted, so I went ahead and bought a 125 gallon tank. It's been up and running about a week and a half now, but I only introduced the live rock 5 days ago.

The live rock I aquired was from another person on these boards, and got it out of his tank. Its still covered in dark purple coraline algae, feather dusters, serveral hermit crabs, and some mushrooms. It was only out of water for about 20 minutes to transport it to my house and straight into my tank.

Should I still expect a full cycle? Or will there just be a small spike? How long ,from anyone else's experience, does it take to cycle a tank this way?
