I purchased a Pentair 720 gallon tank for my imports and a 270. The 720 seems it was dragged on the ground. When putting into storage I noticed I can see through one of the corners, its not cracked and no holes but I can see through it, makes me nervous. I contacted Pentair about this but they don't have a kit to repair. What would be the best way to fix this as I don't want 720 gallons of water on the basement floor.
