Hi. Happy to say, after all these years and different lights used to successfully light my reef system I finally purchased 2 radion xr15g5 pros. Currently running the AB+ 60% and will increase as time goes on. I did have redsea90s running 100% blue white 15k for 10 hours. Happy with that fixture and the results. Just felt I needed more par and a better spectrum. Plus the sales helped. Lol. Really like the color blending so far and just deep the orange reds and pinks. even the yellow tang looks richer. Soft shimmer too. Will use a par meter to dial ot in and get the most for my sos. Positive results.
