Personally have not had radions but had a couple different aqua illumination fixtures currently the prime hd and starting at a lower percent and slowly ramping up to the higher percentage works best until you find the point where everything seems happy. Also keep in mind when adding new frags what lighting they are coming from and either starting them on sand bed or lowering the percentage temperarily. Leds are very powerful I see lots of people running radions at only 50%.

I would back down from 70% to @60% and let your tank settle down. The gradually, like 2% every 2 weeks until you get to 70%. I pushed my lights too quick and burnt up a lot of corals. If you do the mentioned, your tank should come back. Be patient, it takes a while. JME
