Description

How to use: Press the 'MODE' button to cycle through the selection of functions. H: High, constant, non-variable flow (1,000 gph) L: Low, constant, non-variable flow at a third of the speed (530 gph) W1: Short pulses which, when timed correctly will create a back and forth motion and form a gentle standing wave in your tank. Adjust the controller to change the speed of the pulses and vary the size of the wave according to your tank. W2 & W3: Pump gradually speeds up and slows down incrementally to create a varied flow pattern. Adjustable to form the wave best suited to your tank. Else: Reef Stream Mode, a mixed, changing pattern that creates a random flow cycle similar to what you would find in a natural reef. Feed: Press the 'FEED' button once, the blue '10min' light will illuminate indicating that the pump has been stopped for 10 minutes. When the time has elapsed, the light will go off and the pump will be turned back on. Alternatively, press the 'FEED' button again to start the pump. Lock: To prevent changes from inadvertently occurring by accidentally knocking the adjustable control knob, press and hold the 'FEED' button for 5 seconds. The red 'LOCK' light will illuminate and the control knob will no longer function. Press and hold the 'LOCK' light for a further 5 seconds to disable this feature.
