Coming soon to freshwater: HOG2x scrubber® with Xtra light for nitrate over 50 ppm. And Green Grabber® rocky surfaces to hold on to freshwater slime growth.
This HOG2x scrubber® has just been brushed clean, and is a good example of how the Green Grabber® rough rocky surfaces holds on to remnants of growth to make re-growth faster.
The HOG2x scrubber® is the largest ATS solution for freshwater tanks. Most people put it on the display glass, and you can open it for fish to swim inside and feed once or twice a week. The "X" is Xtra LED lights, compred to the HOG2, and strings are not needed in freshwater.
This HOG2x (tm) looks like it was just installed today. The blue tape is holding the black shade cloth (because new installs need less light), and the paper notes are dangling to be read.
