Live Rock curing
 

When you are curing live rock in a new tank should you try and stack it or should you just lay it out so water can get at it?

In my opinion, it doesn't matter so long as you have a good current in the tank. If you lay it out or stack it, there will always be a piece touching someting. Get what I mean???

Curing means to allow anything that has died in transport to decompose. The microorganisms that do this job can do it regardless of how the rock is set up. If this is the tank the rock will be permanently set up in, go ahead and arrange it as you like.
