Radions for 110

[Earl Karl]

Are two Ecotech Radions XR15 Gen4 bright enough for a 110? It is 48x18X30.

Probably not. You’re looking at two XR30s for good coverage, or alternatively 3-4 XR15s.

I did 3 xr15s on my Red Sea 625. It’s larger than yours but a nice spread for lps and softies. I would go w the 3-4 15s depending on what you want in there. Here is the spread of three of them

In terms of spread, 2 will cover that area if mounted high enough. However, you would see a large improvement in coverage and filling in shaded areas by the addition of a third unit. In terms of "bright enough", this will depend on what you are wanting to keep. If you're keeping softies or LPS you are probably fine as those corals in general don't need a lot of par. SPS would require probably 4 of the XR15s (pro versions) (or two XR30 pros) on that tank and you would need to be mindful of placement as I'm not sure they would give you enough par at 30" depth. You'd probably be good as far down as 24" depth. With that 30" tank height, you wind up having natural placement zones allowing you to put lps and softies towards the bottom and high light corals in middle and higher if you like the idea of a mixed reef.
