I was wondering if a 90 gallon tank could be supported by an old computer desk or something of that nature that is made out of wood or steel and is solid. I ask this question because it has come to my immediate attention that Wood stands for a 90 gallon aquarium are invariabally more expensive then the used computer desks that would be utilized as stands. Please let me know. and if anyone has used a used desk or new computer desk for a big tank with success please let me know. and if there are any tests to determine whether or not the desk is strong enough. thanks. shred.
