Keeping eel out of overflow?

[shine~on]

I have a glass canopy for the tank (75gallon) but there is still a gap between the top of the overflow and the back of the canopy. What have you done to block the gap? Thanks.

You can cut out a piece of eggcrate to fit the space and glue it in place. Lighting section at the local home depo sells it.

Ok, I've got some eggcrate but what if I need to get in there for maintenance?

If you can post a picture of the area you want to cover, I can help you easier with a solution.
It is hard for me to visualize the exact shape and way you have it set up.

I'll have a pic up later, it's a reef ready All glass aquarium with built in overflow if that helps. Thanks.

You could try gutter guard. It's flexible so you might be able to bend and shape a piece to fill the gap.
