A friend and I split 50 lbs. There was one piece that was HUGE! Probably 20 lb piece in one piece. The rest was broken up into 3 large p[ieces (although smaller than the one huge piece) and then several fist sized pieces. The rock from SWF.com was anything BUT disappointing. You wont be disappointed at all. The rock had good coralline coverage ( mostly reds and greenish coralline) and that one huge piece was AWESOME!. It was about 2 feet long. So to answer your question, my oprder was a 50 lb order of premium fuji and was better than anything in lfs around here!~
