300 gallon "Outside Corner" Reef
I would challenge that. $1300 are you kidding? A ATS, no matter how fancy the language needs two things, a large surface for algae to grow and a large surface of illumination. I don't use chaeto anymore as I think filament algaes export as much if not more nutrients and grows more densely. My ATS is the same as Dary has except I modified the LED panels. It takes up little room, is easy to clean and cost about $300.
