Anyone running Radion Pros here?

My other problem that I seem to have (and I think other radion users have too) is the fact that my acro polyps only seem to come out at night. I don't think this is a big issue, I'm just curious as to the reason. I do have a yellow clown goby but he doesn't nip, just perches on acros. He actually does this during the night too so I don't think that is the reason they are not out in the day.

This is the first time I've heard this. My SPS have great polyp extension and I know a lot of other people running Radions over SPS and also have great polyp extension during the day. Do you have any Butterfly's in your tank?
 
Yeah, my corals are turd brown, thinking not enough light or I need to get my nutrients in check.

Nope, some anthias, clownfish, wrasse, royal gramma, Kole tang, and a yellow clown goby

Only reason I asked is that I know a lot of people keep flame and coral beauty Angels in their SPS tanks without a problem. I tried it once and the polyps on my SPS would not extend. Never seen him nipping but he must have been. As soon as if got him out the polyps came back out.
