Press the 'MODE' button to cycle through the selection of functions.
H1 H2 H3: High, constant, non-variable flow (4000LPH / 3000L / 2000L)
L: Low, constant, non-variable flow at a third of the speed (2000 LPH)
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.
S1 to S3 Mode: Based on the W1 Wavebox function provides 100% 75% and 50% Wave
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.
