Chiller flow position

[wsiong]

Where would be the better place to position the flow for the chiller....the main tank or sump or rather which would be more effective?

I have a closed loop circuit from my chiller to the main tank.

No sense in plumbing chilled water into the sump first where you'll might lose some of the coldness lost due to heat from the pumps or to waste time going into the skimmer and out before going into the main tank!

Anyway, if there is no way out... then the sump would be fine.. I did that in the past!
