Question About Cycling

[twflint]

Greetings,
Yet another newbie question from me. I set up a new 90 gallon reef tank with 30 gallon sump on Saturday. Couldn't afford 100 lbs of live rock all at once so I bought 20 lbs of live rock and 20 lbs of baserock to get started in the cycle.
Heres my question. I have a 30 gallon FRESHWATER tank that has been up and running for over a year. Would it benefit the cycle at all to add some of my rock from the freshwater tank to my sump (don't wanna get this crappy rock mixed in with my 100 lbs of puka rock I paid for) to help with the cycle?
Thanks,
Troy

Thanks much. Figured it would have to be different, but thought I may as well ask.

I'm pretty sure it's the same bacteria (FW/SW), however, I still wouldn't do it. You have enough on the rock to get you going so why risk transferring something not so good like copper or other toxins.
