How hard to repair cracked glass?

I just bought a 40 breeder setup from waterfowler last night. When putting it on he patio tonight to clean it up we broke the back glass. How hard is this to repair? Sucks it's the drilled pane too!

 

Yeah that would be ideal but there is no rhyme or reason when they have that sale if I remember they just had one in January. I don't want to wait 4 months to get going on this tank.

 

Meeting someone from maquoketa that has a 40b for sale for $30. Hopefully it's in good condition. :crossesfingers:

 

I was already in Washburn twice this week.  My wife is due on Thursday so I don't want to travel too far from home if I don't have to.

 

Yeah I couldn't believe it. Trying to find one up here. My wife is due Thursday so I am not allowed to travel too far now.

 

Took about a half hour to get the old glass off. If I don't meet Shaun tomorrow for another tank I'll try to get a new piece of glass Monday.

 

Three words. It's. A. *****!
   I actually used a carpet cutting knife. It extended out farther than my utility knife. I just made many many passes under the inside of the trim. On the outside of the trim between the glass and trim I rammed a metal putty knife up all around it. You could hear it working. I didn't have much to lose trying it myself. The corners were the hardest to get off. I set up the tank on it's side so could grab the bottom trim and get some torque pulling the top trim. I had a hard time even getting the cracked glass panel out. I ended up just smashing it with a hammer and it pulled out in pieces.

 

Talked with my local glass company and they are getting me a 36x16x1/4" for $21. Not too bad if I can get this sealed back up good.

 

Double post

 

New pane, painted back glass, full tank reseal, and drilled the 3/4" returns. Still need to drill the overflow.

 

Yeah I have the bottom trim on now as well. I was waiting for the wife to get home to help me flip it over.
