I also just got my own shipment of what was supposed to be mixed live rock from aquacon, and was not impressed. They all look the same to me rather than a variety, and were pretty dried out by the time they arrived. Their website says free shipping on live rock, but when you actually go to order they tag on a shipping cost. I had to change my shipping options to ground shipping in order to get the shipping cost excluded, then got an email saying they were coming by air because aquacon sends all live rock by air, and yet when it was actually shipped out in came by ground and was only semi-damp when it arrived. Each rock was individually wrapped in newspaper, which made getting wet bits of torn paper off the rock before putting it in my salt water a pain, and some of the rocks were pretty crumbly when they arrived. I had been really looking forward to the rock based on the descriptions, pictures, reviews, and detailed info from their website about the care they take in packing and shipping. Disappointed to say the least. At least there are bound to still be some living bacteria on it to seed all of the dry rock I bought.
Speaking of dry rock, I ordered mine from bulk reef supply, their 50lb box of figi dry, and another 25lbs of Pukani dry. I am very happy with this rock, especially the Pukani which is gorgeous!
Good luck and let us know what you decide!
