Consider using the cinder block with 2" x4" rack so that it's 3 levels high. Have the bigger tanks on the bottom row. It's the most space saving method I know. (FYI: I can get 21 -10 gal tanks on a rack this type in 8' of space )Purchased a very nice 8'X8' storage building yesterday. I think I may have a free wall for tanks. Been sitting outside pondering how I can most effectively use my extra space.
