Internal overflow question

[albert_dao]

I'm a little confused here; are you gluing a sealed overflow box into the tank? Or are you gluing a box that seals using the back wall of the tank? Generally, you'll want to glue wherever the box makes contact with the glass and needs to separate bodies of water.

I am just wondering if you silicone the overflow right up to the very top of the tank or do you leave a space?

Still confused, sorry, haha.

Is your overflow not the entire height of your aquarium?

Can you post a picture of the overflow box?
