Can't say anything about them as a company, but its so much cheaper to buy mostly dry rock and then pick up a few lbs of live rock from your local LFS instead of buying all live rock. Good places to get dry rock are bulk reef supply and marcorocks.
what about reefrocks.net? They sell base rock for 50lbs for only $85.00. Then they will also throw in 40 lbs of free sand and free shipping. Ever use them before?
