I am making a rubbermaid sump setup with the usual drawer setup for the media. My question is how big are the drip holes in the bottom of each drawer normaly? The setup will have any where from 1,400 gph to 2,500 gph going through it.

I started out with 3/16 inch. If your drip tray fills up to fast and wants to overflow go to the next size bigger until your drip tray fills some but doesn't overflow. You want it to fill some so the water flows through the holes evenly.
