Hey I recently upgraded my lights to Radion Gen 3's from MH on my 150 gallon mixed reef. I was hoping someone who has had the lights long enough could tell me what is the best schedule (preset or custom) to get great colors out of sps.

After TONS of reading and talking to a local coral farm growing nice SPS and a few other high end tank owners and from the personal experience i've had with it i've come to the conclusion that the Radiant Color program at 80-90 percent Is the best for coral growth and coloration. White LEDS burn corals EXPECIALLY 5 watt LEDS reds are also not used much by corals and can burn them. Radiant color program runs 55% overall intensity on the white LEDS and only 37% of the overall intensity of the reds. its basically two hours of 20k in the morning 8 hours of around 15k and then two more hours of 20k in the evenings. I personally tweaked mine so the Blue period was at a higher intensity in the mornings. I run my lights from 930A to 930P my tank is sps heavy with RBTA and various lps on the bottom all very happy. just start at 40 percent and VERY gradually work your way up keep in mind that these lights are honestly no joke and will burn your stuff up right now. HAPPY REEFING

also SCHWINGS graph runs no UV big mistake in my opinion that is one of the aspects of this light that really make it "shine" no pun intended when it comes to growth

Also i'm not sure if any of you read far enough into it but SCHWING or whatever his name is Grew all that coral under ATI sunpower t5's and switched to radions shortly after tearing down the tank

There is UV in my schedule, but I just really like the overall look of my tank using his schedule. If I start getting problems with it I'll definitely use the radiant schedule then. Awesome to hear some input!

I am also using this light schedule but there only issue I have is the setting the lunar phase. I currently have 2 gen3 Radion for my 120 gallon. Have anyone tried else tried modifying Schwing schedule? I've tried add more points after sunset for the lunar phase but it refuse to turn on. Getting pretty frustrated. Please help!!!!!

I tried moving my gen 3 pros to 75% but some of my sps started to loose color (on radiant color pre set). On the borderline of bleaching.. I was at 65% for a while then bumped it up over the course of 2 weeks to 75%. Im at 70% now but I think im moving it back to 65%. 80-90% seems super intense to me.. Although I wish i could bump it up that high just for the overall look of the tank being that bright. Oh, also started to get a lot more algae growth when i hit 75%..
