LF - 33 gallon long tank

[lodidodi]

Does anyone know where I can get a 33 gallon long tank? I believe the dimensions would be 48 1/4 x 12 3/4 x 13. I'm looking to build a sump under a 75 gallon aquarium so it doesn't have to look good, just hold water.

OR, does anyone have any suggestions for something else I can use?
