Designing a 120

[Reefhawk1]

Hi folks

I am in the process, slow process of designing my 120 gallon tank. I have ordered my glass drilling bits and I am going to attempt to make swiss cheese out of it.

I have a few of questions

I want to make a strong current in the tank, what is the best way to achieve maximum flow ?

I am going to use a center overflow system How many 1.5 inch drain holes should I drill?

What are you using for high flow return pumps? any recommendations?

Thanks
