Guys, his tank is 24" x 18" at the top, not 24" x 24"! LOL. He said 24 high. The "depth" part thats throwing you is front to back "depth". Anyway, if you yourself are handy or you have a handy friend w/ tools, making a hood is pretty straightforward. Theres not much to them, and you could prob. do a better job and cheaper too. Look around on this site for DIY plans. Good luck!
