    This HOG1 or 1x is pulled out of a large saltwater sump. This size HOG is too small to do enough filtering by itself here, but it can help, and the growth can do all the herbivour feeding by just dropping it into the display for a day or so. Note the top 1 inch is flopped down; this is where the waterline was.

    This HOG3 or 3x or 3xx from saltwater shows very dark slime growth in the middle, and cyano on the lower outer parts. This is probably a HOG3, which has most of the light in the middle, and less light on the outer areas, because cyano grows in a scrubber usually only if light is low, when nutrients are high. This combination of cyano and green slime holds a lot of nutrinets, but must be brushed out more often because it does not hold on well, although the Green Grabber® rocky walls are doing the best it can (a regular waterfall screen could not hold on to any of this).
