Odd question maybe

[Dez]

Some of you might have been following my tank build. I have rock that has been in essence "cooking" for 4 1/2 years. I started up a new tank and it's heated and salted.

1. Do I have to RE - "cycle" the tank - ie - add some dead shrimp or something to start the cycle?

2. If I seed the tank with about 5 lbs of really nice rock from my nano would that be enough?

Right now, technically there should be no cycle cause my rock has been in dark, heated, salted, and relatively high flowing water for 4 1/2 years.

3. When is it safe to start stocking?

Thanks so much. All of my tanks I've started with fully cured good live rock, so this is new territory for me.
