lol. that would be HUGE. if i had a tank like that, it would be for rays. dunno how it would be to have all the water pressing against the one side of the tank either. unless it was all concrete with just side windows
The only problem I see, is that the water level on the one end would be real low because of the position of the overflow at the other end. Otherwise, it would be really sweet!!! Too bad you can't turn a semi trailer into a big tank......
