Mesenterial Filaments. Can you force them to retract?

[GoFish]

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

pics?

 

[GoFish]

Oh yeah sorry forgot to update this with pics. I've had some discussion going on another forum...
#1....gave up on and removed from the tank this morning, it continued losing flesh
#2 and 3....were recovering nicely until this morning, they'll get a few dips in iodine for the next couple days, fingers crossed
#4....still brown and has barely any polyps showing
#5 and 6....still alive but barely and may end up being placed in the shade for a long time and see what happens
50% water change when I get home

Im confused...
1-this picture looks beautiful.
2-I thought peroxide was what got you into this mess...why did you treat another rock with it?
3-Ive never heard of a dose of peroxide screwing up coral that bad. Ive had a few palys get burnt with straight 3% as an experiment lol but people have dosed tanks with it to get rid of unwanted critters with not too much damage.

This thread is interesting I'd enjoy seeing two week updates

It is unlikely the peroxide would have killed anything, mesenteries are not lethal they are valid space regulation organs and food acquisition organs for corals...clownfish nipping brings them about commonly or chem events. Trying to make them go back in is stressful, the coral self regulates them

Any recent lotion use on hand + my tank makes a lobophora digest half the corals around it


The temp stress and iodine dipping are far more stressful

There are methods of peroxide use that never contact unintended targets, but even for the instances of total contact there's no recurring losses for species shown above, they aren't on the known sensitives list

Cant wait to see how it works out

With peroxide only having a half life of 24 hrs, wait it out and observe more than reacting. 50% WC can throw everything off unless parameters are matched perfectly, nutrients included. I agree w/ Brandomn that these are all hearty species and should not respond this way. Another school of thought would be that treating that rock caused a massive die off resulting in an ammonia spike.

Oooops sorry meant to post the aftermath photo! Here's the nasty stuff...
Not certain it's the peroxide alone that caused it, there's likely other factors involved. The nuclear green palys were fragged and relocated as well as the purple death and pink zippers at the same time as peroxide treatment. There's also the fact that a furan 2 rinse of the same rock was done at the same time as I found the base of many of the zoa heads were basically rotting from detritus sitting there. I should have had a routine of blasting the rock with a turkey baster at least a few times a week to prevent this. This will be done frequently from now on...
"Ticking time bomb" was mentioned on the other forum, could've been doomed with this potential issue for a while. And the day the peroxide Furan treatment was done was just and avenue to make it happen.
Paly toxin...peroxide....Furan...stress. I'm not sure what was more to blame

Really good documentation there and nice cam work ~ I think many of those can come back

and just might be invader free

 

[GoFish]

Ammonia spike was a worthy mention^^^^
Really old API test kit but looks like it shows the presence of ammonia?... and high nitrate. Not a fan of colour change tests... I forget the science behind cycling but this probably isn't good.

Just got home... Coral #1 is definitely dead on the window sill. The monti has zero polyps out. Fingers still crossed for 2, 3, 4, 5 and 6

 

[brandon429]

i noticed the tank was free of coralline and age indicators...id have been looking for a sump or some area using aged material as filtration media...how did you cycle the tank

 

[GoFish]

Oh there's coralline all over both rocks, no need to cycle this stuff. It's been in 4 of my tanks (4 years+) And it's an all in one, I used to have hydroton in the back all in one chamber but it was too much. If you can have too much biological filtration?

 

[Oceansize]

IME, you'll never get the API test for ammonia (saltwater) to read anything lower than that. The freshwater one will read 0 when the tank is truly 0, but the saltwater one never seems to read absolute zero even when there truly is zero ammonia in the tank. That light green is about as good as you'll ever get in SW.

I don't think that level of nitrates would be problematic for any coral except for maybe SPS, and even then I'd still be skeptical.

 

[brandon429]

agreed w both above. can't have too much filtration, worst case scenario is nitrate sourcing but that's not happening here, bone clean setup. yes it all looks very mature to skip a cycle, considering no fish bioload heavily pushing things. imo its all in the multi stressors and any singular one prob would have been ok. still I think many w recover
