Expected coverage for a XR30 pro gen 4

[chaostactics]

If centered over a tank generally what length, width, and depth would one expect each unit to cover in order to get adequate (not stellar) growth from sps coral?

You would need to play 20 questions first...how high above the water line? How deep is the tank? At what intensity and spectrum? Are you planning to use any filters/blending?

30×30 ×22" deep and any height under 15" inches and any intensity if it works for that size coverage, spectrum i usually use the coral lab setting or whatever its called

I think the Pro versions claim 30"x30" coverage but IMO, you still have dim edges. I run four Pros over a 72"x24"x24" to reduce shadowing but that's just me.
My old 30"x30"x 18" needed two non-pro XR30s for adequate coverage if that helps.
