Burns11, have you considered purchasing uncured rock? I have purchased cured rock from one of the places you mentioned, i'm not going to say which because I have nothing but negitive things to say about it. It was almost compleatly barren with only about 10% covered in coraline. Even a couple years later nothing really good came out of that stuff. Theres a well known supply store that I won't list here because I don't want to get into trouble for posting outside links. They have a wide selection of rock that i've been considering for a new tank. You can get cultured fiji rock from them for about $3.00lb. Premium Fiji for about 3.00lb or cultured carabiean for about $2.50lb or Tonga for a lil over $4.00lb. Also they have a 16lb box mix ment for nano cubes, but I bet they'd put togeather a larger box if you wanted, consisting of rock from Fiji, Tonga and Indonesia for $70, and that's precured. I've never ordered live stock from them, but always buy my dry goods from them. They've always been very friendly and knowledable. Also another place that has always been very honest and answered all my questions has a wide range of Marshall Island rock for about $5.50lb uncured, Vanuatu for $5.00lb uncured about 6 differnt types of Tonga for $3.75lb uncured or Fiji for about $3.25lb uncured. These prices don't include shipping. If you want the links please send a private message and i'll give them too you.
Never believe a place that tells you their pacific live rock often comes with stony corals attached. According to U.S. custom laws all unidentified corals are to be confiscated, that means they can seize live rock that has them as well. Because of that they always remove stony corals from pacific rock before shipping. The only rock you'll get corals on is the caribean cultured.
