Mesenterial Filaments. Can you force them to retract?

[Go.Fish]

Yesterday i treated a big piece of live rock in the tank with Peroxide and neglected to properly rinse the rock before placing it back in the tank. Subsequently I came home many hours later to realize it stressed the crap out of several LPS corals. Including 2 Chalices and 3 Acans. They're honestly in pretty rough shape as of this morning.
Wondering what the best course of action would be. I did a 20% water change and plan on doing another one in the evening. I'm thinking of trying to guinea pig one of the Acans in a cold tank water bath (with an ice cube) and see if that will make it retract. Other than that I'm at a loss. My first thought is getting all remaining peroxide out of the tank if it hasn't lost its effectiveness by doing water changes and move the corals to low light areas.

Will post a photo when I get home

Thanks in advance if anyone has experience/suggestions

Assuming the lighting is sufficient and your parameters are within reason the only thing you really can do is be patient. When the coral has settled down those filaments your seeing should retract.

I would not subject the already stressed corals to additional stress (cold water bath). Water change to remove peroxide.

I was thinking if the mesenterial filaments would retract it would make the coral look more normal. And hopefully recover quicker and be less prone to infection. I tried a coldwater bath on #3 as it's my least favorite, it didnt appear to do much at the time, but its in the best condition of all the pieces so maybe had a slighty beneficial effect. 55 degree tank water for several minutes

Before pics are what these corals looked like before peroxide
Treatment was done on Wednesday...
After pics were all taken the day after peroxide (Thursday)
Current pics were all taken last night (Saturday)

Just added this thread to the general reef forum with more info.

A better way of looking at it is that the filaments are a coral's necessary stress response since it has evolved to have that response for some reason. Trying to circumvent that reaction is only going to cause problems.

Picture that your natural reaction to heat is to sweat; in that scenario heat is the problem and once it has been removed you will eventually stop sweating. Treating sweating like the problem means you get dunked into a vat of ice water and catch pneumonia.
