Customer's HOG scrubber® taken out of a saltwater sump. This one would be a HOG3 or 3x or 3xx because the wet side is the same; the difference is in the lights, which you can't see here.

Some HOG scrubbers grow mostly on the strings, and some grow mostly on the Green Grabber® white rocky textures (dark slime does this), but this one is growing on both.
