I purchased a 75 gallon reef ready oceanic tank w/ hood and stand from someone on rc. It is a beautiful tank, I am absolutely in love with it. Well, I decided to take things easy, and buy the rest in pieces, so I wouldn't kill myself financially. When I bought the tank, the guy had all his bulbs and pieces in the bottom of the tank, so I didn't get a chance to look at the bottom. I asked him it held water, and he said yes. I was starting to set things up yesterday, and noticed a chip in the bottom of the tank that had been sealed with silicone. It is less that 1/2 of a dime size. What should I do? I filled it 1/2 with water, and it didn't leak, but with rocks and sand-that is much heavier. Should I give it a try and set it up.
