A month is likely not enough time to really have your corals adjust to a powerful light. That said, if you arent happy, making the switch is all about what you like. The ATI fixture isnt "better" that the Radion, its just different.
What arent you happy with the Radions? Is it just because of the coloration in your corals? Are you running the Coral Lab Program, or are you just winging LED programming? It might be worth taking a look at Ecotechs work on the Coral Lab (link
here) to see if an adjustment to your lights will help your coral health
Hmmm... how many Radions do you have for your tank size? A common issue with LED fixtures is not having enough spread to provide a nice blanket of light across the entire tank, which is what T5 fixtures often provide. For what its worth, I run a 8x80w ATI fixture and I love it. Ive run LEDs before and had success with SPS and loved them too.
