Need a some thoughts from others more experienced

[bigjonbird]

I just drilled my 40 breeder and put overflow box as you can see in the pictures. I am worried about the overflow box leaking or causing issues. If someone has been down this road before, I need your thoughts on what to do. The way I see it I have three options:

1) Leave it as is
2) remove the rubber gasket between the glass and overflow box then add silicone to bond box to the glass
3) I could drill overflow box holes bigger so the bulkheads do not grab the box and silicone the whole box to the back of the glass and the bulkhead is installed normal, right against glass

Thank you in advanced for all the help. I just recently broke this tank down due to crazy brown algae and restarting with a newly made sump as well. Trying to start this tank off right.

I suggest to test it. It looks fine to me. Fill it with tap water and see what happens.

I think,,,, as long as you have a rubber gasket between the back of the inside box and the glass you will be fine.

Water test.

What's going to be on the outside?

Thanks, yes there is rubber between box and glass as well.

I'm just running 90deg elbows connected to vinyl tubing that goes into a sump. I ate up a little more room on the inside of the tank without the external box but I wanted to keep it simple. If it doesn't work I can always redesign it.
