Are you capable of making your own? It shouldn't take much effort. You would just need some materials from a hardware store, a plan, and some good ole' fashion American ingenuity. You could probably make a better (functioning) overflow then could be bought.

What size tank? How much flow do you want to design for? Do you want an internal, external, or over-the-back type?

the hole that he cut is a 2 inch hole... and it is for internall overflow

The simplist approach might be to just install a bulkhead, and make an acrylic box with a few slots on one side.

Use glass instead!

Acrylic does not bond well to glass. I would suggest using inexpensive pieces of glass to create your overflow. Here are some photos that I got off of someone's thread, unfortunately I don't remember from where. I apologize for not being able to give credit where credit is do. This is how I plan on doing mine over the next few weeks.

Also, you can put eggcrate on the top if you want a teeth-like effect.

Hope this helps! Best of luck!
