I am finely board with the hobby time to down size! So It begins!

I guess the first thing I have to think about is a stand construction, materials, height and what it is going to house? I am a tall man 6'4" so height is not much of a problem. I would like a big sump at least half the volume of the main tank running water volume 140g. So 180g tank would work 72"x24"x24" none drilled. To house a sump like that it would have to be a metal stand. Now the skimmer I would like to double the main tank volume so 600g or more. Height of the stand plays here. I would need to get equipment in and out for install and cleaning. I need some advise on skimmers? I do like the Asm even thou the are old tex.

I figger the base of the stand would be 72 1/4" x 30 1/4". reason for the extra 1/4". No tank is exact dimensions. The metal stand would probable made out of 2"x2" square tubing. Height right now depends on the skimmer. my thinking the sump would sit on a 3/4" plywood and foem so 1 1/2" the same would be for the main tank. 3" of height is used up add in the top and bottom 2" square tubing 4" equals 7" of height used up.
