This person's video shows our smallest Hang-On-GlassŪ scrubber HOG.5 in freshwater, and it's filtering the water and feeding the fish at the same time:

This looks like Ulva Fasciata species, growing in a customer's HOG1 or 1x. It is upside down in the photo.

An example of how strong illumination can "penetrate" through algal growth in this customer's scrubber, which looks like a DROP1.2 or 1.2x. This penetration keeps the LED lights from getting covered, and allows the light to penetrate deeper into the growth.

A rare all-bright-green filled SURF4 or 4X from a customer. Usually there is a mix of colors of growth.

This is a little more common; a mix of light and dark on a customer's SURF4 or 4x. Note the dark growth is around the edges where there is less light. If the walls were not bright-white rocks like they are, there would be much more dark growth around the edges and the growth would let go quicker. Dark slime growth does not hold on well, even though it contains lots of nutrients from the water:

If growth gets up to the light, as on this customer's SURF4x, the growth might starting growing on the light itself which reduces illumination. So more frequent cleaning of the light would be needed (with a piece of plastic, etc)
