One Cubic Meter of Ocean

[Scythanith]

So you put the returns on opposite sides of the sump mostly due to space constraints on the left side of the upper sump correct?

I wonder if I should ask Denny to change my design to have the two returns on the sump side by side? The stacked design may give me similar issues. If we lower the sump then we take away the silent aspect of the overflow box to sump don't we?
