Anybody here have a real fish room?

I have a 70 tank fish room (tanks are 10 gal - 75 gal)I am set up mosly for breeding not for beauty If you want to maximize space set the tanks with the narrow end foreward and stacked side by side This way you can get 4 10 gal tanks lit by one 4 ft light fixture Use shop lights from home depot to save $$ Building racks will depend on the tank size and the their weight If you dont want to go thru a lot of cost hears a way to make a rack for10 gal tanks Buy cinder blocks and 4X4s in 8-10 ft lengths(an alternate is landscape timbers of treated wood ) stack the cinder blocks as high as you wish to first tanks to sit put the timbers in the opening of the cinder blocks You can stack additional cider blocks to make 2or 3 more levels Each level will hold 8 10 gal tanks stacked on end
