Lighting for 40B.

[cymonous]

I am setting up a 40 breeder. I have lights from a tank I am downgrading from. They are the SBReef lights LED box. The basic model less than 2 years old. My corals will be LPS. I may in the future get an anemone. Can I use just one LED box, or do I need two?

I would say two if you want full coverage in a 36” x 18” area. you could also add a few T5s to get coverage on the two ends
