Ricordea Yuma after dip.

[LokiDawg]

I purchased a yuma colony and did a bayer dip. About 500ml tank water and 20 mL bayer for about 10 mins.
Ive dipped other coral at much higher concentrations with no I'll effects.
However, the yuma don't look so good now. Idk if they're just trying to acclimate, or if the bayer burned them. They're mouths are open and the orange appears to be retracting.
Any experience? Advice?

Maybe it was placement.. Moved them closer to light and they seem better.. I thought these guys needed minimal light and flow.

I would just leave them be. I wouldn't give them more light as they are stressed. I've never had luck with yumas. Many do though. I would just let them recover and monitor them. Some GAC might help.
