| no... not really..
a closed loop is a system where water is pulled in through a large pump and immediately shot back into the tank....
think of a big powerhead, but instead of the regular spout, you attached pipes and stretched down the length of your tank, with many nozzles pointing in many directions...
that's a closed loop..
now the SCWD would come into play as a way to switch between two spray bars or pipes of some kind in your loop..
