I saw on the CCY page that some one has a 110 with stand for 200.00. that is deeper than a 75 or 90 but it should be a 4 ft tank. and that is a great deal.
I have a black trim 48"x18"x18" I think it comes out to be a 65 gallon. $65 and it's yours. Or I have a 75 gallon oak trim that is 20" high for $75. Pick up 22193.
