Two overflow means that I have two areas in the tank where the water spills down into the sump. I did not want just one overflow in the middle because of the aquascape plan I have in mind, I wanted full depth in the middle.

Hi, i want to buy a 72x24x24 Acrylic tank, but i was wondering what thickness should it be, the sale person said 1/2 inch is enough, is it? What do you mean by 2-overflows? Is that mean 2 return water from the sump?
