Various upflow growth pictures

This tiny DROP.2 is starting to fill in with slime

This looks like a SURF2 or 2x or 2xx lifted up out of saltwater. Reach in and grab

This HOG3 or 3x or 3xx scrubber® is partially lifted out of the water, and is still bubbling on the right side. It might look like the algae (looks like Cladophora sp) is just sitting in a bowl, but it's actually attached very strongly to the Green Grabber® rocky textures and strings and won't fall out. A tang would live to be swimming in there.

The two growth compartments of the SURF8 scrubber® let you clean/harvest one side while letting the other side continue growing and filtering. And only 3 inches of water surface depth is needed; all other space below the scrubber is open for your rocks, pumps, etc.

SURF2 harvest from saltwater. The water level is just below the arrow.

The "wet" side of the small HOG.5 scrubber® pulled out of saltwater. This looks like the early stages, with thick slime, which needs brushing off in the sink; the black plastic shell needs brushing too, as well as the air tubing. The white Green Grabber® rocky texture holds on to slime well, much better than plastic screens of waterfall scrubbers. Slime also absorbs the most nutrients...

Feed your fish from your scrubber.

Free, fresh, and does not add nitrate or phosphate to the water like normal feeding does.

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

Here is a vintage SURF4 floating, and with lid up, and with growth removed from a saltwater sump

This HOG1x growth is from saltwater, and could be brushed out or pulled out by hand. A brush is better here because of the darker slime growth on the outer areas. Also the holes in the bottom and sides, and the hole at the top, should be brushed clean, as well as the tubing at the bottom. When brushing the tubing, it helps to have the air running so you can see how well it is bubbling.
