SPS tank - Switch from T5 to 2x Kessil A160EW - Thoughts?

I must chime in 😀 sps coloration is based on keeping steady ideal parameters over months if not years. Lighting has little to do with coloration. Yes you can get coral pop with high k lighting but your corals will still be brown if your nitrate is to high and phosphates are detectable. If you can get coral pop under 10k led mh or t5 than you are approaching mastery.
My experience is with the 360we over two years now but on a smaller tank I am sure you will be surprised with you 160ew
