new tank question
 

hello i am upgrading my tank from a 60 to a 120 tank .my new tank will be ready tommorow and i would like know if its ok to use as much of my old water as possible ?also can i add all the salt water right away or sould new tank sit for a few days with only fresh water then drain and refill with salt?

I just do a freshwater scrub and rinse.

If you're adding new rock to the overall setup I'd suggest letting that run in the new tank first to avoid a cycle...

Also, its a good idea to do a leak test with fresh water rather than saltwater :-)
