Depending on how good the stand needs to look, you can put together a 55 gallon stand for less than than $10. Get six 16" x 8" x 8" concrete blocks. They cost $0.96 each now in Menards. Homedepot or Lowes should be similarly priced. Stack 3 rows high on each end with the holes vertical (not like in the picture below but it is really a moot point because the blocks can support so much weight). Select one of the best 2 x 4 x 8'. It should cost between $2 - $3. Cut it in half (the store may do it for you) and lay them flat on the concrete block. If you want more security, you can use 2 x 6 or 2 x 8. The picture below does not even use that but a 2x lumber is beneficial, IMHO. You can hide that rudimentary stuffs with drapery or bed sheet or . . . Glass tanks only needs to be supported around the four corners.
