so right now i have 2 tanks on the main floor of the house one 140g and one 75g all within 10ft of one another in the corner of the house... and im thinking about upgrading to a 220g in place of the 140g i have ... so i would purchase the 220g and break down and move the 140g outta the corner and stuff the 220g in there and sell my 140g to recoup some cash ...anyway here are some pics to give ya better idea of how the tanks are setup, please excuse the mess from my kid lol he still tiny .. and yes my basement is finished but we NEVER spend anytime down there ever lol.... all though i looked in the furnace room (unifnished) and can see the floor joist in it... now if they are all the same through the entire house then they floor joist would run the depth of my tank 19" and 24" depth of the new 220g, house was built maybe 8-10yrs ago ....would i be safe to have a 220g in place of my 140g ?
