Work in progress. Got a great deal on a 90 gallon tank (48" x 18" x 21"). I built the stand out of 2"x4" pine. I'm gonna build doors and close it in when I get some free time. I built the stand 36" high, great for viewing and I can still get my arm in the tank. I know the rock work is a mess, I'll fix it up when I get more time. I transferred everything over from my 55 gal. and didn't want the rocks to dry up so I just placed them in for now.
