At the risk of asking a stupid question...lol, I been wondering if it is at all possible to combine two 10 gal tanks together to make one big 20 gal? I was thinking you would remove the bottom and set it on top of the other and apply some sealant , I thought I saw a post where someone did that but realized they were just two tanks on top of each other, not combinedwould this be possible to do? if so how would you remove the bottom out of one without busting the glass?
