Agree with above... my only caveat is to look and try to confirm where the leak is coming from. Our 210g had a leak and we were sure it was on the end, but upon closer inspection, a seal on a bulk head in back was bad. We replaced it and no more leak. The water was dripping down the back and running around the edge of the stand to leak off the end. So try to be sure, just in case it is an easy fix. Good luck.
