I definitely have better coverage but I'm also running more radions than you are suppose to. I am only running them at 43% right now.
So yes I have coraline everywhere haha. Overall I think that growth is not as good but color is better. I have had parasite issues so that is attributing to the slower growth as well. I have noticed that some sps just doesn't like LEDs, but that has nothing to do with the radions. I noticed the same when I was running my diy units as well.
All that being said, I love the LEDs. My temp barely moves anymore so my chiller was in the closet through the summer.
