I know, hence the needing slow sump flow, or a REALLY large skimmer that would be so costly as to make the FIFO design not that appealing.


But really, in a sump with your skimmer, how much water is being recirced by a regular one pass skimmer in a sump chamber? Sure, you match sump flow to skimmer flow, but there is allways skimmer outlet water that will be sucked back into the inlet. Only true way to ensure that doesnt happen is to feed skimmer from different compartment.
