    Here is a customer's HOG3 in high-nutrient saltwater, and positioned slightly above the waterline. The high nutrients cause the very dark green slime growth, which is loaded with nutrients from the water (darker = more nutrients), and the air bubbles and salt spray are kept inside the case so that only air goes out the top hole. This dark growth will need brushing out with a toothbrush in a sink; once enough nutrients are removed from the water (which takes a few weeks), lighter colored hair algae usually grows, which can be pulled out by hand.

    This customer's HOG3 or 3x or 3xx in saltwater, on the display glass, shows it's growth above and below the waterline. Nutrients are lower in the water here, allowing for lighter colored growth to occur:

    Customer's high-nutrient saltwater causing thick dark slime on this HOG3 or 3x or 3xx scrubber®. Will need cleaning with a toothbrush in a sink, often, until nutrients in the water come down enough for green hair algae to grow. Or add another scrubber to bring down nutrients faster.

    Remember though, that dark slime algae has the most nutrients in it from the water (the high concentration of nutrients in the algae makes it dark or black). So as long as you harvest/clean it OFTEN, it pulls out a LOT of nutrients from the water. But it must be often, like every 3 or 4 days, because slime does not hold on well and will let go and float away. And you can't pull it out with your hands, so you must take the scrubber to the sink and toothbrush it until you see the white Green Grabber® rocks again.

    Note the left side is bare; it was above the waterline, acting as a bubble and salt spray remover.
