What does the top look like? Is that the only entrance to the overflow?

I guess you can choose more or less surface skimming. I believe the water level in your tank when your pump is off in this configuration would be determined by your standpipe height

I think the theory back in the day was to pull water from a lower portion of the tank, in addition from the surface, for better circulation.
