I'm looking for a stand that will fit a standard 55 gal inside it as well as on top. This means I can prepare water underneath over night and pump it up to the display tank for water changes.

Standard 55 gal aquariums are 48" x 13" x 21" OR 122cm x 33cm x 53cm.

If you've got some of these tanks available I'm also interested in them, but the stand is what I'm primarily after.

Thanks, Ben.
