OMG! What did you do? What did you do that for? J/K, you drilled the bottom I'm guessing? Can't really tell on the phone. If you drilled the bottom you have options. You can build an overflow, like on my tank, or just a stand pipe. Looks good though. BTW, don't put silicone between the gasket and acrylic. Don't know why people always think this is a good idea, silicone is a lubricant. And don't over tighten the bulk heads, finger tight and a little more worked for me.
