    Small SURF in small compartments

    This SURF2 or 2x scrubber® is in a small saltwater sump compartment, and is not affected by the salt splash buildup.

    This SURF2 has four deep red 660nm LEDs inside the waterproof heavy weight sound-deadoning lid, and looks to be a new installation in a saltwater sump (skimmer is on the left). Since the ultra white color of the Green Grabber® strings and rocky textures make the red light too bright for algae growth, a black shade cloth is included and should be put over half the light until some color of growth covers the white surfaces. No other color of LED (blue, white, UV, etc) is used, because unlike trees, algae prefer pure red light.
