I'm attempting to determine the best way to plumb in an external skimmer, as I just ordered a Regal 300-ext for my new build. My initial thinking was to feed it with a COR-20, and have the water exit the skimmer into my frag tank, being the sole source of return water for the frag tank. It hadn't occurred to me at the time, how much of a problem micro-bubbles might be...are they as bad on an external skimmer as they are on an internal one? Is the exit into the frag tank viable, or do I need to re-think the plumbing and have the water flow out of the skimmer directly back into the sump?
I am trying to utilize 2 return pumps for my system, 1 COR-20 for the display, and another COR-20 for the skimmer and frag tank.
