Storing Live Sand

[Dez]

When I set up my new tank is it going to go through another spike of some sort? I've never upgraded before. I'm going from a 90 gallon to 150 gallon. All the rock and coral and water from the 90 are going into the 150 (with the new sand) So it's going to be adding about 60 gallons of new water. That's a good thing right? Sort of like a 40% water change. Who else has upgraded tanks before that can give me advice?

Thanks so much..
