Yep, biggest concern I've read. I am starting both blues at 35% and whites at 30% with a ramp up and down time of one hour. I have 8 70 degree optics coming to swap out the 4 front and 4 back optics to give better spread in the front and back. They currently are about 14" off the water and are covering the entire tank very well.Budsreef;645009 wrote: That's very cool! What do you have the levels set at? It's very easy to burn your corals especially under the 40 degree optics if you haven't swapped them out so go slowly.

So far, I've seen dramatic color and growth improvements since switching from the AI LEDs.
