    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.

    This SURF2 or 2x is drained out, and on the top and left you can see the white Green Grabber rocky walls; this looks like maybe it was setting at an angle in the water.

    Packed SURF4 or 4x showing what looks mostly like Cladophora species, and maybe a little Ulva Fasciata. It is growing on the light too, which needs to be scraped off with a plastic card (like a credit card) to get the most illumination into this growth.

    A new SURF2 or 2x with light removed, and black shade cloth which was covering the left side. Since the left side was growing more, and was shaded, this tells you that more of the area should be shaded so more can grow. Once growing, the white surfaces will reflect less, and the shade cloth can be removed.

    This DROP1.2 scrubber is ready for brushing out; the Green Grabber® white rocky surfaces are better at holding on to this growth than waterfall screens are, but this particular type of growth growth cannot be pulled out with your fingers.

    This DROP1.2 (tm) UAS® upflow scrubber is pulled up from a saltwater sump and is full of cladophora species growth. Note the growth on the upper back right; it has pulled away (in a block) from the white Green Grabber® rocks on the back wall because some of the growth was attached to the door when it was opened. All of this growth should be pulled out for harvesting, and the door (on the left) should be brushed clean.
