Man, sorry I know this is the internet and shorthand is more liberally used, but damn..
Sorry, mini rant done.
Okay, on to the issue. Lets get some stats. What does your NitrAte measure at, because if your tank is cycled, you shouldn't need a NitrIte test anymore. What size is your tank? What do you use for water movement? What is your Alkalinity, Calcium, and Magnesium measuring? Zoas don't really "bleach" as much as other corals do, from everything I've seen. What are they doing that makes you say they aren't doing well? Why do you think a dip would help?

Personally I use Seachem Reef dip(Iodine based) but Coral RX is considered gentler on the coral than anything with iodine.
I have also used Hydrogen peroxide as a dip for zoa's mixed 1:4-5 with tank water (ex. 8-10 oz of tank water then add 2 oz H2O2), gently agitate for about 5 minutes.
Make sure it is getting some flow as well.

If your zoas bleached out you did the right thing by moving them down immediately. You may still lose the colony anyway, but, you took the correct precaution. I'm guessing that the tank that they came from wasn't lit by LEDs or if they were then the zoas were probably near the bottom. I bring that up because anytime you move any coral from a T5 or halide tank to an LED tank light acclimation must be done, I learned the hard way at the expense of a couple of montipora. Also, not all zoas are created equal. There are some that you can nail to a wall then put them back into the tank 3 days later and they'll still be fine, but there are others that if a soft breeze blows in from the west(looking at you stratosphere zoas) they'll melt. If you're going to dip them coral rx should be fine for now and place them in a low light spot near or on the bottom so that can hopefully recover.
Yes.
Original poster, please take the time to phrase your questions more coherently. It shows you value others' time as much as you value your own.
