Mine is not a tank room per se. Tanks in my garage is a better description, but I hope to have that remedied in the not too distant future. After setting up 4 , I got the no more tanks in the house memo from the boss. Originally I was just going to do a couple out in the garage, but somehow that evolved a bit. Here it is (excuse the mess) as of today, but changes are coming.
I have to work the tank to the left which is 7x2x2 and these other projects into the mix.
5'x3'x27" 250 gallon
8'x4'x27" plywood around 500g
