Recovering from a bleaching

[Ephraim]

So for some unknown reason i thought i would be a good idea last week to do a water change, put in some fresh carbon AND change a bank of t5s. Now i have bleached out most of my monties and pavonas. The acros are happy as clams though.

The questions is, how do i help these poor light stressed corals out? They are all pastel but other wise look healthy. i have moved the lights up so much less light is hitting the tank. Also started dosing reef roids nightly. Any other tips to get colors back asap?
