I just purchased a Waterbox 100.3 and now researching which light to get. I absolutely love the flat minimalist look of the ATI Stratons and am leaning towards that. The Waterbox display is 35.4"×23.6"×21.7" (LxWxH). The Stratons looks big so I was thinking one is enough but the website says it only has a 30"x30" spread. Does that mean I will need to purchase 2 then? I am leaning towards a mixed reef tank
