any new breakthroughs on the ATS? I was going through some figures and though the ATS is a great option for the tank as i used to run one till about 2 weeks ago, the ATS uses more energy and cost of bulbs per year will end up costing you more than a Skimmer. I'm all about energy efficiency and saving a buck, but i think that a LED solution needs to be made. I seen on Cutter.com.au that CREE has released these to grow plants
http://www.theledstore.com.au/category_s/35.htm so it may work with a scrubber. I'll be ordering some near the end of the year when i put in a large order for a customers tank that I am building.
it uses: 3 Red 625nm, 1 450nm Royal Blue , 1 Red 660nm
