Pretty sweet setup!Thank you. By running a manifold you can run one pump for everything. Return, carbon, biopellets (if you go with them) and anything else that needs a feed pump. My system is ran by a single jebao dc6000. This feeds my carbon/gfo reactor, my skimmer and returns water to the tank. Here's and example of what I mean. Basically you "T" off of your return line to feed other equipment.
Hope that helps
