One big pump to run everything?

[Milad]

Im just finishing up my new shed which is housing a few tanks that will be my sump. I was thinking of using one large pump as a return, feed the tank for the skimmer, feed the bio pellets, feed the AC unit, feed the carbon reactor, ATS, etc

Is this doable? Does anyone foresee any problems? In theory this should all work as long as I have some resistance per "channel"? Im going to have a ball valve on every channel the pump feeds.
