Bleached SPS Recovery

My tank is 90 gallon without sump or chiller with 2 x 250 metal halides lights. The A/C went out and the top of my tank got up to 90 degrees. I have had a few of my sps bleach out but they show signs of coloring slowly returning. I only lost one frag from this. Since then, new a/c until and I am running my lights at night so I don't have to fight the daylight heat.

My question, anything you recommend to aid in the recovery process?
