[KMP]

OK, wheels are turning on the chiller return issue. Let me explain how this will be plumbed and then I have another idea...

Looking at the diagram, the small top hole would have flex tubing drawing water in. The second small hole would have flex tubing coming back into the sump, but hooked directly to the pump which is pushing water to the skimmer.

Regarding the skimmer. The ASM G3 is up for sale as it's been moved to the side for an ETSS Red Devil Twin Tower skimmer. The design of this skimmer brings water in from the top and comes out low in front. So, I could feasibly add a partition between the chiller intake and the pump/skimmer.

Make sense? Critique away.

Another thought is; if I were to plumb the skimmer to exit directly into the refugium area via a bulkhead would that create to much disruption (water flow) in the refugium?

If the sump was set up like this, a partion wall would not be necessary as there woud be continuos plumbing from the chiller, through the pump, through the skimmer and out into the refugium preventing the chilled water from ever mixing with the water coming in from the tank. So I guess the question is; is flow in the refugium a bad thing?
