Before the radion, these same zoas were under the ai and open all day.

And how do you figure that 12 watts of red LEDs are beneficial to corals?

This weekend I'm going to try this out. I'm gonna have the reds on only, for the first 5 hours of the day. And I'll take a time lapse video of a zoa frag to see if it'll even react (open,close,twitch) at the red light

that'll be a very interesting video! I love time lapse haha.

As I said above the Radion is double the power and full spectrum totally different beast. I loved my Ai's at full bore, the radion is way brighter at 130w vs 70w i run one radion now where as before i was running two ai's

I never said that running all red would give great results, or be the miracle coral growth formula (in fact it wont).....but you said that. the red and green LEDs were useless, which they arent.....the red spectum gets filtered out of the water very quickly so deeper water corals tend to not take to red very well, but shallower water corals will benefit from lower color temperatures....the radion provides probably the closest to full spectrum lighting as wee can get atm
