    Re: closed loop system?

    A closed loop system has plumbing designed to deliver water from and to the tank without going through a sump. For example, a drain pipe feeds a large pump under the aquarium. The pump then returns the water flow to several inlets located throughout the back of the tank. The system is entirely closed.
