I bought a used 120 gallon tank from bostonpop on mr. Me and a friend picked up the tank and the guy said nothing is wrong with the tank. I get it home.fill it up everything seems fine for three days. Then I wake up to a flood. I call the guy and he admitted the leak and said it wasn't that bad and he glued it. Well since yesterday I resealed the leaking overflow. I transferred everything into holding tanks with alot of casualties. Im so mad I lost my powder blue, three cleaner shrimps, peppermint shrimps, sixline, bubble coral and a few acan colonies. Hopefully no more as im starting to put the 120 back up.
