"That's exactly why I turned down my brother's offer to give me his 220 and took his 60 gallon glass and 80 gallon acrylic tanks instead. 220 gallon is alot of water on your floor if something happen.. Best thing you can do is make sure the seal is new and pray every night to the fish god "
I'm purely speculating, but I have a hard time believing that 220g on your floor is that much worse than 80g on your floor. In any case, both would really, really suck.
