So what size lines are those and what size pump exactly?

Intake is a 2" line & returns are 1" so when running its a even ratio of 2 - 2. The pump is a Dolphin 3600 GPH. Loc-lines calculate out at 2 1/4" per return.

Thanks, what do you mean ratio of 2-2?

Oh OK so actually you have a 2-1 ratio relating to area (2^2 : 2x1^2)

Actually now that I think of it, it's really a 1-1 ratio related to water volume in & out. I might be totally off here because of an 19 hr day yesterday.
