Good deal, i'll say that much! I mean even if it is dead when you get it, curing it will be worth it, as most "cured" LR isn't cured at all and hits a cycle neways.
That is an amazing price. The MAX conference is in Orange County, so it would be a great time to verify this company in person. If you needed a lot of rock, getting it in person would be roadtrip worthy. Saves on shipping.
for me i would rather buy just dead rock from bulk reef supply which costs from 1-2 a lb or just go on craigslist where they sell live rock from 1-3 dollars
