The Pump Shut-Off temporarily turns the pump off if the water level gets too low in the Filter Tank, and turns back on when the float is in the up position. The waterfall will cycle on and off, giving a visual indication that water needs to be added to the system.
NOTE: A Pump Shut-Off is highly recommended, especially if an Auto-Fill is not installed. If an Auto-Fill is installed, the pump-switch must be positioned lower than the Auto-Fill, otherwise water will never be added.
