I am looking at buying live rock from liveaquaria.com and I think I'd like to get the larger, more porous caribbean rock vs. the premium Fiji which seems smaller in size and more dense. But... it says the caribbean is uncured. Everything I've read says to make sure it is cured. What problems might I have if it is uncured? It will go straight into the tank to begin the cycling. Snails, crabs, etc. to be added once algae starts. Thanks.
