i got the package to start my 55 gallon reef tank about 2 years ago. i agree with tcarlson - partly. the hitchhikers (evil crabs and mantis shrimp) are a big PIA, but the crabs are pretty easy to trap and feed to the starfish, and the shrimp can be gotten if you perform some preventative actions before you put the rock in the tank for the first time, like dunking the rock in very saline water, or freshwater. The critters that you get are definitely a bit much, like the cukes, and the pistol shrimp, but i didn't mind all the hermits. that said however, the rock is amazing. the life that you get on it is truly awesome. there is amazing color to the rocks with all the sponges. all the other rock i see, whether its fiji, kaelini, whatever don't have this kind of life on it,(admittedly i haven't seen all that much high-quality live rock). i had tunicates, barnacles(which a mantis made quick work of), hardcorals, macroalgae, and other stuff. one other huge plus is that they ship it underwater, so you get very little dieoff, a huge plus in my mind. also, i got a little goby with my live sand. with regard to it being too much sand, once again, i agree that you don't need all live sand to start off with, thats why you can use quite a bit of it to start off your dsb in the fuge, or another tank, or whatever. its not the cheapest way to start a tank by any means, but all in all, i think the beauty of the rock outweighs any of the negatives.
