I was looking at this setup Niko posted , and would like to plan for it in my new fish room.

I want to drill overflows on my tanks for easier water changing, not necessarily for sumps.

Is it better to drill a tank on the side or the bottom?

Is there a step by step guide somewhere on these forums or elsewhere? I've looked but haven't found many?

thanks for any help.

Some aquariums have tempered glass on the bottom,
so drill on the side glass.
