Bumping this thread, got the fixture hung today, just want to say first off it’s AWESOME! I absolutely love the spectrum of the T5. I did coral plus, blue plus, radion, blue plus, coral plus and switched the spectrum to my radion from a WWC preset to AB+ as I was looking for a more daylight spectrum to enjoy the colors of my fish. I set the fixture at 9” and have the xr15 set to 60%, the t5 I currently have running for 6hrs coming on about 45 mins after the xr15 hits peak, and turning off about two hours and forty five minutes before the xr15 ramps down into the blues of AB+. Can anyone offer any advise to this? Tomorrow will be the first day of the t5 for the full six hours so I will monitor the corals throughout that time and see if any thing looks unhappy. Any input on my schedule is encouraged and greatly appreciated, thanks
