Can't regain polyp extension

[daniella3d]

Hi,

I have an acropora that was very shaggy with extremely long polyps but since the Kent contaminated charbon there is practically no polyp extension and it seem to be getting worse rather than getting better. I did like 7 water changes after the event and it was looking better and better but now I stopped doing the water changes because the analysis on my water showed no more trace of copper or heavy metal but why is it going worse?

Should I keep doing 30% water change even though the copper is gone?

Anything else I can add to the water that will help polyp extention?

I just bought 2 new frags and they are millepora and have great polyps extension even after being a week in my tank.

It lost a lot of color but it is not bleached completely. So sad, that acropora looked like it had fur before.

Here is the before:
