That picture looks an awful lot like the stuff listed on Ebay by "ereef1". I fell for it and bought 100 lbs. It took a week just to get it shipped after I payed for it. It is UNCURED live rock and it was all but dead by the time I got it. It took 3 weeks with weekly water changes out in my garage before I could put it in the tank. It smelled so bad it stunk up the house for the first week.
That web page doesn't list an address, but I would be willing to put money on it that this is the same guy out of Mirimar, FL. If you have the time and patience to cure the rock yourself, it is a good deal. If you are looking for cured rock that you can put in your tank, stay far, far away.
BTW, I purchased this right before Christmas. It is still in my tank and I am pretty happy with it. It just took forever to come around. The only hitchiker was a small tube worm.
