I think you would probably be better off with 3 a360WEs instead of the 160s. I have 160s on one tank and they are great for LPS and softies but not for SPS. If I had more of them, they'd probably be better, someday maybe. I also supplement with a 2 bulb T5 fixture. I have another tank with 360s that I have no issues growing anemones, only have one SPS coral and I haven't killed it yet so it must not hate the lights. So it kind of depends on what your ultimate goal is. I love the light they give off, it is much more natural looking to me than others I have tried. The shimmer is like no other and you don't see the individual colors like you do with most LED fixtures. I also use their controller to control the lights. One controller controls both of my tanks.
