    Green and red Holiday colors in this HOG3 scrubber in the middle section of a saltwater sump. Big growth in a small space.

    This is a rare photo of cyano filling up a scrubber. This SURF4 or 4x has contained a lot of the floating red cyano, without letting it escape out the drain holes on the bottom. This cyano will be removed/cleaned/harvested with the regular cleaning of the scrubber. You don't see this amount of red cyano on a waterfall scrubber screen because it would let go and wash away.

    Only Green Grabber® surfaces, like in this DROP1.4x scrubber®, can hold on to so much slime.
    Note the LEDs (arrows) burning through the slime.

    This HOG.5 with just a single LED light has been running in shallow saltwater, about 4 inches deep (probably because no deeper area was available), and you can see the waterline where growth occurs only below the line. Keeping the upper part above the waterline provides a benefit though... it keeps most of the salt spray inside the case, and make it more quiet too.
