[Oilers]

I was looking at my tank and I noticed there was some water on the floor. It wasn't much so I thought maybe the fishes have splashed some water out onto the floor. However, when I inspected more closely, I noticed that there was also water at the top of the stand where the bottom of the tank touches. I took some paper towel and wiped everything dry. After an hour or so, I found water in the same place again.
Is my tank leaking? If so, how do I find where it leak? Is it fixable and how do I do that? Is it worth it to fix or should I find a new tank since once the tank leaks, it can leak again in the future. What should I do? HELP!!!

PS A friend of mine told me that the problem might be when I started using the easy blade scraper attachment for the cleaning magnet. The blade might have cut into the silicon that holds the tank together.
