anyone use this type of live rock. get 100 lbs of it on ebay for 320 bucks free shipping. its UNCURED though. how long would it take to cure it. i would do it in buckets seeing as im still in the SLOW SLOW learnign process of reef keeping. i figure i could get the rock and let it cure while i research more and pay money on the tank and light i have on hold at the LFS
