Need to find out how much force would it take to pull up 650 gallons of water into a tank from the bottom by sucking out the air from the top of the tank? Also how much vacuum pressure would be inside tank once full? I am basing this off an upside down fish tank. Example on youtube or like the upside down dog waterers(adsbygoogle = window.adsbygoogle || []).push({});
