Hole Sizes?

zoohoot · 11/08/2009, 09:16 PM

I am ordering my custom tank this week, and wanted to confirm what is recommended as far as the pre-drilled drain and return holes. The tank is approximately 180 gallons, with the overflow in the dead center of the tank.

Here is what the builder recommended:

1 - 1" drain hole
2 - 3/4" return holes

Does this sound right? Any changes recommended?

Thanks!

My 120g has twice that, I guess it's going to depend on the size of your sump and how much you want the water to exchange from the display to sump.

This will be my first tank with a sump, so I want to be sure to get it right. So you have 2 drains and 4 returns? Are those the sizes you have?
