Looking for hob overflow that is just like hob filter

[andyl9063]

I am looking for a hob overflow box that acts just like the hob filter. I want it to pour water down into the tank.

Anyone see one like this before?

Not sure I understand the question. You want it to overflow and go back into the tank? OR overflow and go down to a sump?

The first would be a regular HOB and the second would be a regular overflow box.
