    Multiple scrubber styles for different areas of larger sumps. This also lets you decide what style you like better.

    This SURF4 or 4x (cannot tell without counting the number of LEDs) is overgrown and sticking to the light.

    This is why you need waterproof submersible lights for a scrubber in sump water. Yes this is a SURF light, and not a screen.

    This is a rare photo of cyano filling up a scrubber. This SURF4 or 4x has contained a lot of the floating red cyano, without letting it escape out the drain holes on the bottom. This cyano will be removed/cleaned/harvested with the regular cleaning of the scrubber. You don't see this amount of red cyano on a waterfall scrubber screen because it would let go and wash away.

    Packed SURF4 or 4x showing what looks mostly like Cladophora species, and maybe a little Ulva Fasciata. It is growing on the light too, which needs to be scraped off with a plastic card (like a credit card) to get the most illumination into this growth.
