I gotta look at the height on this acrylic tank sitting in our basement. I've never used it. I believe it was DIY but it just came with the whole setup I got into the hobby with nearly 3 yrs ago. You can have it. It's drilled with two bulkheads, dividers, etc. Pretty sure it's 18" tall but I can check.
You can have it free if it'll work for you.
