    Not spaghetti and meat sauce. Looks like a modified HOG3 or 3x or 3xx scrubber that needed brushing out (in a sink) a week ago. Slime it still good though...

    This SURF4 or 4x (or half SURF8 or 8x) shows the strings circled around 3 of the 4 holes where the upflowing air bubbles come up (red arrows). This demonstrates how the air bubbles create vertical pathways for light to shine down deeper into thick growth, which cannot happen with waterfalls.

    This DROP1.2 (an older one with clear tubing) looks like some growth has been pulled out by hand. For more filtering, you could brush the surfaces off in the sink under freshwater.

    This DROP1.4x (older model with clear tubing) shows how the 6 high power LEDs burn through the growth.

    This type of slime growth on this RAIN4 waterfall scrubber in saltwater really needs the screen, tray, and pipe slot to be brushed clean every 3 or 4 days, and would do best with an optional Slime Screen so the slime can reallly hang on. More light is not the answer, as you can see, because the light is strong enough to make a growth ring, which is about as strong a light as you can get. More info:
