Dark thick growth like this customer's SURF2 or 2x is loaded with removed nutrients from the water, but must be harvested more often because it detaches easily. Stronger lights would have grown a lighter color:

Growth in a customer's tiny DROP.2 which is the smallest scrubber in the world:

Dark slime growth like this customer's HOG2 scrubber is loaded with nutrients absorbed from the water. Just be sure to brush it clean more often, in your sink with running water, because it blocks light from reaching the "roots" and thus will let go and wash away more easily.

This is more common: a mix of different types and colors and growth, as in this customer's SURF2 or 2x

This is another rare all-green customer's SURF4 or 4x

Here is a HOG1.3 or HOG2 in freshwater; these are better for FW because they don't have strings (strings are better for salt). Looks like it was just brushed clean in a sink, which is what you do with freshwater growth because it's so thin and slimy. Note the brave fish tail in the very upper left of the customer's scrubber picture.

Freshwater growth, in a customer's newer HOG2 scrubbers. This person has four of them. Scrubbers like the HOG2 and others without strings are best for freshwater:

Here is a customer's really new growth on a HOG1 or 1x. Growth has just started in the middle and has not spread to the edges yet.

This customer's HOG1.3 is a typical growth amount for newer tanks and less feeding. When feeding increases, the scrubber growth will get thick quick. This looks like saltwater because of the thicker Ulva Fasciata growth, but the HOG1.3 is also great for freshwater because there are no strings to brush clean (strings are best for saltwater).

This person's SURF2 or 2x shows a type of saltwater growth that occurs sometimes. It's a bright green, thin, jell-like growth that looks like a combination of slime and green hair. But it probably has some bacterial film growth too. It requires taking it to your sink and brushing under flowing water.
