I had alot of problems getting my 400 oceanic 3/4" glass tank moved too. I had several piano moving companies look at it and say they couldnt do it (they all showed up with less than the 6 people minimum I said could even lift the thing). Holey Mackeral Aquariums finally got it done-- it took 8 HUGE dudes to move it with piano dollies, high end suction cups, and brute force. It wasnt cheap but I was relieved to get my new purchase home! Apparently there are no returns once the previous owner drains 400 gallons of salt water on his lawn (I bet he still cant grow grass!).
