I rum most of my system off my main return from a reeflow it works well its a small dia return line dont think it reduced my overall return flow that much. i also have a closed loop from a second pump but my reactors/UV/ all except skimmer are taken off my return , ive reduced flow from each off line to accommodate the different reactors etc. very clean and less energy/heat added.
