I notice my sump water in the last 2 chambers seems to get a film deposit on the surface. Oily gunky stuff. I'm using a Vectra M2 return pump so moving 800gph through the sump but still have this stagnant looking surface film.
Is it OK to put a small circulation pump in the skimmer chamber facing the surface to ripple the water? Won't the water movement also help oxygenated the sump and move detritus?
Any negatives?
