    Customer's SURF2 or 2x or 2xx filled in. This is with the water drained out. It is very thick and could be pulled out with your fingers.

    Customer's DROP1.2x from a saltwater tank. Lots of slime, pulling out lots of nutrients, but needs brushing more often. Every 3 to 5 days probably. Also note the light brown spots where the strong red LEDs shine through the growth.

    Customers DROP1.4x from saltwater, with unusually thick Cladophora growth all over, including on the Green Grabber® surfaces on the door. This growth is easily pulled out with your hands.

    HOG3 or 3x or 3xx scrubber® showing what sometimes happens in very high nutrient water: Very dark/black slime oily growth has trouble holding on, and lets go, leaving white spots. The Green Grabber® rocky textures hold on as good as can be expected (much better than waterfall screens), but can be further helped by maximizing light to 24 hours, and brushing clean every 3 days. Here is more info on slime:

    All our upflow algae scrubbers® stay underwater all the time, so if the power goes out, the algae stays alive for a long time. And you can just let the fish eat the growth, so that you don't add new nutrients to the system when the power is out and there is no filtering. Pictured is a HOG scrubber® feeding some freshwater fish.
