Noob needs help/tip with live rock

[jason604]

Ok so I bought 70lbs of live rock today and I left it about 1.5 hr out of the original water. I used my clean spare water I use to refill my pond n put it in a large bucket to mix the salt n put the rocks in. The thing is the water was 5deg c when I put the rocks in. I was afraid that the rocks might have died if I didn't put it in soon. There is a heater and power head for it and the water is now at about 20 deg. Did I screw up and killed everything from the really cold water? Also how do I start my cycle? What do I do. I'll have a proper tank in 2 weeks. Please advise me with some your Ur long term knowledge lol
