so I browsing CL, and found a 210 gallon aquarium, that the guy says leaks due to a crack in the bottom band but not in the tank itself?... I didn't know the plastic band on the tanks held water from leaking??? I he only wants a $150 for it... what do you guys think I was considering selling my 55, my 40, and 2- 20 gallons to get this and having this tank and my 75?should I risk it or do you maybe think there is a real underlying problem with why this tank is leaking??
