Adjusting Water Level
Adjust the height or angle of the return hose back into your
aquarium to your specific needs.
If you have chosen to use the RETURN NOZZLE, you can
turn the nozzle to face upwards for more surface tension or
downwards for more movement at the bottom of the
aquarium.
If you have chosen to use the SPRAY BAR, adjust it so the
small openings in the spray bar are angled at a 45 degrees
angle so it breaks the surface of the water for more gas ex-
change.
