    This saltwater customer's SURF2 or 2x is growing and filtering well, but notice the yellow in the middle. This is where there are fewer air bubbles. The air bubbles bring water in, and with the water comes nutrients, especially iron. Iron helps the growth stay dark green.

    The growth here is thick enough to keep the bubbles from flowing to the middle, and so the middle does not get enough iron this week. A good cleaning/harvesting will do wonders, as will feeding anything with iron such as nori or veggie pellets.

    This SURF4 was floated in the display of a reef (so no sump was needed).

    Here is a bunch of Cladophora algae (it grows in both fresh and saltwater) in a customer's HOG2 or 3 or 3x or 3xx Since you can't see if strings are under the growth, you can't tell what model scrubber it is...

    Customer's HOG3 or 3x or 3xx in saltwater, with very light colored growth. Just like vegetables, darker growth means more iron is in the growth, and other nutrients too; so you can add iron to the water (with supplement drops) or feed more seaweed like nori or algae pellets to the fish, which will also eventually get more iron into the water, and make darker growth:

    Slime!!

    Well, this is good. Dark slime has the most nutrients concentrated in it, taken out of the water. Just clean it often (with a brush, in your sink) before it lets go...

    Customer's HOG3 or 3x or 3xx in saltwater that is well seasoned. Air tubing at the bottom should be kept brushed clean.

    Here's a customer's HOG1 or 1x in saltwater, although it's also fine with freshwater; the growth should eventually spread to the sides:
