What to use for dipping corals that don't open?

[Pimba]

I have some duncans that's been doing great for sometime but stopped opening for about 2 weeks now.

I've read that dips could help. My question is what do I use to dip with iodine or hydrogen peroxide or something else?

I am not sure I would dip with anything at all.......dipping is only going to irritate them more IMO. I personally would let them be...duncans can sometimes become angry like that for weeks at a time lol.
