Here is some pics of my newest scrubber, its a week old today. Its powered by 4 reds (660nm) and 1 blue (450nm) per side, this give it the purplish glow. I removed the UAS as it was not working on this 150G tank. The UAS has been fine on my 10G Nano. My UAS grew hand fulls of thick algae and you would have thought it was going to be great but sadly it was not. I hope to get some pics Monday as it will have a true 7 days growth. I finished it last Sunday evening. I think its great to have another dedicated scrubber site!!! Thanks Bud!!!
