Drilled tanks?

[epond83]

So i keep hearing it's better to have your tank drilled for your overflow.

I'm researching stuff to set up my own sw tank and just wondered if any one had this type of set up and could post up pictures?

Thanks

Here is a drilled tank with 2 overflows and 2 returns.... the other tank is a QT tank so dont pay attention to it.

Thanks, yeah i get how it works i guess just seeing an actually picture of the over flows would be cool also i'm thinking more of ones that are drilled near the top.

The bottom drilled are a better option, there will be less flow resistance as you will have less bends in the piping.

Drilling into the back near the top will work though!
