HOG3

This anemone tank has a HOG3 or 3x or 3xx on the front of the chaeto compartment in the sump. The light is from the chaeto light, hanging above the sump.

Feed your fish from your scrubber.

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

Green and red Holiday colors in this HOG3 scrubber in the middle section of a saltwater sump. Big growth in a small space.

This is probably a HOG3, overgrown whith mostly Ulva Fasciata.

This HOG3 or 3x or 3xx from saltwater shows very dark slime growth in the middle, and cyano on the lower outer parts. This is probably a HOG3, which has most of the light in the middle, and less light on the outer areas, because cyano grows in a scrubber usually only if light is low, when nutrients are high. This combination of cyano and green slime holds a lot of nutrinets, but must be brushed out more often because it does not hold on well, although the Green Grabber® rocky walls are doing the best it can (a regular waterfall screen could not hold on to any of this).

This is the wet side of a HOG3 or 3x or 3xx taken out of saltwater. Almost can't tell which end is up, except for the air tubing on the right side, which is up, which means the bubbler is on the left, which is down.

First, this should have been cleaned/harvested much sooner, because when it gets this thick (about 2 inches) the light can't reach the bottom layers as well, and those layers start dying. The extra light in the 3x and 3xx reach deeper, but still get shaded eventually.

Second, the yellow in the middle is from lack of iron/nutrients, because:

1. The thick growth blocks bubbles from flowing through, thus reducing nutrients to the growth.
2. The thick growth is pushing up agaist the glass, which is nearest to the light, so it gets more light than it needs.
3. The thick growth blocks/covers the water circulation holes in the case, further reducing nutrients getting to the growth.

So for max filtering and nutrient reduction in the tank, this scrubber should probably be cleaned/harvested or fed to the fish every 5 days or so, and when doing so the entire inside of the case should be brushed with a brush in a sink with running tap water to kill the pods.

However if the goal is to just grow pods for the fish, you don't have to clean/harvest at all. Just let it run, and pods will grow and come out of the holes to feed the fish. Maybe you'll need to unclog the circulation holes a bit. Or you could modify them larger, say 1/4" diameter.

Or if the goal is to grow algae to feed to the fish, then you just open the case and let the fish swim in and eat overnight, then put it back into operation for another week.

Here is an old BRS post of I think was a HOG3

This HOG3 or 3x or 3xx wet-side looks fairly new, and is still filling in

This is probably a HOG3 scrubber® or larger. Can't see the strings, but it would be difficult for a model without strings to hold on to this much growth in saltwater. Even the stronger light in this model is having trouble cutting through the growth to get to the back wall, and thus the growth on the back is darker. So in addition to cleaning off the circulation holes more often, the light should be run 24 hours in this case, and cleaned every 5 days or so, including brushing the Green Grabber® back wall with a toothbrush in a sink, so you see the white again. And of course don't forget to clean the glass before re-attaching the HOG to it.

Or, just put the whole things into the display overnight for the fish to eat.

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...
