Can't regain polyp extension

The new frags have great polyps extension, to the max I would say, and great color so I guess it is not something in the water but rather that the shaggy acropora is still in shock. Strange, it's been 3 weeks since that event.

Have you looked at the acro at night?.... Does it extend when the lights are off?

+1 for Brad's advice.

I had a temp probe fail and my system dropped down to 71f. It took 3+ weeks for corals to recover.

Cheers,
Tim

Yes and at night only the polyps at the end are coming out, nothing else is even coming out. During the day the other polyps are coming out a little but bearely and the polyps at the ends are hidden.

What worry me is that the coral has some filaments out like if it was still attacked. When I put in Kent carbon it was full of these filaments for a few days.

This hapened on February 9 and it's been 3 weeks and half and things seem to be going down hill instead of improving.

Can the coral still have heavy metal in its flesh and be dying from it? if so what can I do?

Some part of my sps have started to RTN, and yesterday evening I could see lots of filments out, this morning there was absolutely zero polyp extension, so the coral will probably die from the poisoned carbon and never managed to recover from it

Another casualty to add to my list of dead corals from this carbon

Since the polyps look better at night with lights out I would try to shade the coral during the day.

No, that's the thing. there is absolutely zero polyp extension at night.

There was a little bit at they end of the day before the light went out, but at night even the tip polyps were retracted.

Also I took a frag and the skeleton seam very fragile, very brittle and break easily. Is it possible that then heavy metal poisoning have affected the coral internal structure?

Maybe hydrogen peroxide fill fix it?

Daniella i have the same variety and every now and then when water changes, moving etc occur it takes them a few weeks to recover they get really shocked and will not come back out. But eventually they come around if all your levels are good it will eventually come back around. My suggestion is to let them be and they should come back, by fragging it and playing with it you may be adding extra unnecessary stress to it which will lengthen its recovery

I only fragged it when I saw that some part of it was RTN. It was going better when I was doing daily water change but since I have not do a water change in a week, it went downhill pretty fast. It's like the flesh is getting more thin by the days and the skeleton is getting fragile. I don't yours ever got copper poisoning...not sure it would come back.

I had that coral bleach before and lost polyp extension but like you said in a few weeks it was going better and better. Now it's the opposite that is hapening, it is going worse and worse with less and less polyp extension and flesh going thin and disapearing in patches.

Water parameter are great, calcium 420, mag 1400, alkalinity 7.5, nitrates, etc...undetectible with my tests. All other corals are doing great with great polyps extension and last test done on my water showing no level of copper what so ever (below the pro laboratory equipement detection), so there is no more copper in the water.

It is very wierd, as if there is now only some green and brown color on the skeleton and no flesh or a very thin layer of flesh. It used to be plump and hard and when I was touching it, it was not falling apart.

I tried a Revive dip on the frag I did and I put it in my nano. I will see if it will come back.
