recovering bleached LPS

[asylumdown]

Does anybody have any tips on how to recover a bleached LPS? When I started my tank I had all 8 radions running at 100% for 6 hours a day and I put in all my 'tester' LPS pieces that had been in my 5 gallon pico.

I have a decent sized chalize colony that has gone from red and blue to pale pink and white, and an elegance coral that is so bleached it's practically translucent.

I reduced the max power on the radions to 70% for a few weeks (increasing from 65% over the course of 6 hours), and when I added some SPS frags I upped it to 75% (increasing from 70% over the course of 6 hours). The SPS loves it, everything that was browned out when I got it is now exploding with colour, and an open brain I bought when the lights were at 70% hasn't bleached at all, but the pieces that bleached at the beginning aren't improving at all.

Should I move them under a rock in to the shade completely, or are they toast?
