I got three boxes of the Premium Select Liverock from them back in August/September. The rock was pretty plain with hardly any coraline algae. So, I emailed them pictures and called as well, took a couple calls, but they acknowledged that the rock I received was not representative of the rock advertised on their website. The livestock manager told their rep that they had just received some really sweet live rock with excellent coraline algae, so I told them to make it four boxes.
The rock arrived fresh, with decent coraline algae coverage 50-60% and was obviously fresh...had that nice fresh, ocean smell. The shapes were shelving pieces, some craggily pieces and some boulder pieces. There were a few sponges and coraline algaes, but that was it. Nothing live on the rock unlike fresh live rock in the past that was covered in algaes, some corals and hitchhikers. I think the rock they sell is definitely a great value for the money, but it isn't like the "live rock" of old about 10 years ago. I assume that the rock is cleaned, then held in fresh ocean vats to make it very clean, almost sterile, then shipped in to the states. I would definitely buy more and am satisfied with the rock, especially the price when it goes on sale, but it isn't like the rock crawling with interesting critters, macros and corals of old.
