Just patch it. It would be a huge headach and cost a lot to replace the glass. You can either use a bulk head and put a pvc plug in it or get a small piece of glass that is about 1/2" thick and silicon over the hole on the inside of the tank.
 
yeah i have a bulkhead in it now but really wanted to putnew glass and drill it for closed loop but this will be ok thanks alot
