Radion XR-15 intensity suggestions

[Tallison]

what is the suggested intensity for 2 Xr-15s 12-14 inches above the aquarium? It's a mixed reef with a few nems. Any pics of lighting schedules would be great

The AB+ schedule is proven to be a good program. I run that at 70% intensity. Make sure you do an acclimation.

Awesome, I was originally on the apex profiles that topped out at 60% then moved to 70% on AB+ and my nems started moving. Wanted to make sure 70% wasn't too much

If I go over 70 I start getting some bleaching of lps. My montipora loved it higher but 70 is a good balance for me. Of course a acclimation is a good idea with leds.

Besides height above the water, it's going to depend on how deep your tank is too. I have mine about 9" above the water (standard RMS mounts) over a tank that is 18" deep, and run them at about 45%. There are a lot of variables so you need to just dial it in for your particular situation. Best thing to do is either get a meter and aim for a certain intensity at a certain point in the tank, but even with no meter just slowly ramp up the intensity and keep an eye on whether things continue to look better or start to look worse.
