I appreciate the concern cccapt, but I looked at that center brace before doing that. And I think that the integrity of the tank is still there even after drilling the holes. But to be on the safe side I will glue down a strip of acrylic to not have any mishaps. Here are some pics just as promised.
Have a piece of painted acrylic to go on the back of the tank but not putting it up yet as I am still setting up everything.
Thats a piece of my framing that I have right next to the tank. Still have to do one more coat of poly, so it should be up in the middle of next week.
