    SURF4x

    This is a low-power mode of the SURF4x. It is a pattern of 6 of the 12 LEDs, connected to one of the power cords. The other 6 LEDs are connected to the other power cord, and when both are plugged in you have full power. Low-power lighting (combined with shading from the included black shade cloth) is usually needed on new installations because the bright red light is reflected off of the white Green Grabber® rocks and strings, making the light even brighter; too bright for algae to grow. Once growth occurs, however, you need the bright light to travel through the growth to keep it alive and growing.

    SURF4x packed and ready to harvest. Looks like two of the four bubble pathways have filled in.
