I just call a wholesaler in Cali and have them ship me some boxes to DIA - I just ordered 500 lbs of Fiji for a new build. Even Hydroids cannot likely live through the curing process. Most pests come in on the small rock that wild corals are attached to, or frag plugs - there are plenty of people with dry/dead rock tanks with all kinds of pests. Rock shipped in water will also be full of pests - this is one of the few reasons that I avoid TBS rock.
livestockusa.org will ship it to you. Any good LFS can order you rock by the box as well.
