Hot, Hot, Heat - The after effects

[KPG007]

I finally got the chance to go on a week long halibut / salmon fishing trip last week and absolutely loved it. Unfortunately the tempreture around here shot up through the roof and my fish tanks (I have two independant 33g systems) got hit hard. My girlfriend did everything she knew (which was really only the basics) to keep the temps down but they still got up to 88f. Finally one turned for the worse, one fish died then the second (this was my frag tank, so only 2 fish), SPS started to RTN all in the matter of a day and a half. So far fish and acro crabs are dead, and 60% of my SPS are RTNed or are RTNing.
When I returned from my trip, I managed to save my display tank (although it looks like it's right on the edge), and then started the process of rescueing the remainder of the frag tank. All tanks are now stable at / around 80f, a 50% water change in the frag tank has been done, and a 10% change is planned for both tanks as soon as I can get the salt mixed. Both tanks have a mechanical filter running (Rena XP3's) and have fresh carbon in them.
Now here are my questions:
- Will the SPS that have areas of RTN recover now that the system is stable again or will they continue to die?
- The skimmers on both tanks (just the hang on style remora's) are putting out no foam even though they are clean and working properly.
- I realize the bacteria in the live rock took a major hit, and it will take a few weeks for them to recover. Is there any way of speeding this up? Zeo7 or something similar?

Thanks;
