I'm setting up a nano reef in my room from my old equipment and am jumping around with what tank size I want to setup. really I'd like to setup my old 29g. I have 2X 2 bulb T5 Nova Extremes that I can use for lighting, I'll probably get a glass top to cut down on evap. I have an Octopus HOB 100F skimmer that I'm going to use and should have an ATO sitting around somewhere.
my dilemma is that the 29g I have has an imperfection on the glass. I've had it setup before with this, but it was a planted tank then and there was less money at stake if it did break (plus I was less worried about what happens it the tank cracks/water get everywhere).
its a chip that is inside the glass- the crack doesnt show up on the outside; its about two inches above the bottom seam, you can't feel it if you run your fingers along corner seam, its smooth.
here's some pics:



how concerned should I be? I can see the area from across the room, which is the only thing that makes me worry about it.
I have a 40g breeder that I could use but that's kind of a big tank (really not much bigger than the 29, I know, but its a bigger footprint); also if I go with the 40g I have to get a new light which I'm not thrilled about.
