this is a mod posted in the web (not mine-i'm "borrowing" pics). seems like a good idea and it applies recirculation. Pang 2014 and the likes because the modded skimmer is a SeaClone.

i assume with vin's impeller mod and this recirculating mod it would make a Weipro 2014 (which i have) work well. The vortex/turbo/centrifugal design was totally blasted out. Maybe it will work. Assumption pa lang.
