Hi guys, I'm new here and definitely i want to build an ATS here. I've been battling high nitrates for so long that's not even funny but I want to keep my fish and corals well fed. What if I want to feed 4 cubes and a sheet of nori every day? How wide and how long would I have to build my ATS? And what'd be the wattage i'd need to light the sheet?

Thanks for your help guys!!
