Live Rock/Base Rock Question

[Myka]

You could cook dried out rock in tap water. Are you using tap water for the tank? If you are using RO water for the tank you should cook in RO water at least though since you will probably contaminate the rock with heavy metals and organics from the tap water. However, it would be wise to finish the cooking with saltwater for the last couple weeks to get the saltwater well flushed into the rock, once you do that add a few pieces of cured "real" live rock to seed the previously dead stuff with bacteria and oter life forms. If you cook the rock properly, and don't have the rock out of the tank long when transfering into the display you will not create a cycle.
