new or old water?

[thresher9]

I'm switching tanks today and just thought of something. Is it possible to shock live rock? Should I put my live rock in old tank water or use new water? Eventually it's going in the new water, but can i just use my old water for now since it take a really long time to make water.

Yes, you can use old water but depending on how long your old system was running you might stir up a lot of stuff. Are you using your old sand too?

No, I got all new sand. So I guess I'll put water as much water as I can in the tote before moving the rocks around. But putting the rock in the new water without acclamation wont kill anything right?
