Hey guys a few of my zoas are smaller and wont fully open I was going to try a iodine dip. I was wondering what the proper was of doing this is?
Chris
Hello Chris, sorry your zoas are having issues. In fact, your zoas may not be having any issues at all. I think we dip far too often when it may not be the advisable first course of action. It's best to try and fine the root cause of your problem which most often can be done with a process of elimination. By back tracking, checking your parameters, make up water source, amount of internal flow, how long the polyps have been in your tank, aquisition source, temp, visual inspection and a dozen other reasons. If a dip is performed, and you are still having the same issues, then you have come full circle and right back where you started. This is why I feel it is best to dip lastly and not first unless you are dealing with an obvious host that can be seen, i.e. Flatworms for example, or visual signs of sickness. A lack of internal flow alone could be the cause of your small zoas and lack of expansion alone.
Before dipping, I would first ask....
1. What are your parameters?
2. Type of testing source?
3. Source of make up water?
4. How long have they been in your tank?
5. What size is your tank?
6. Type of lighting and age of bulbs?
7. Amount of internal flow, not turnover?
8. Do you have any other polyps besides the ones not expanding?
9. Where are they located in your tank in refernce to flow source?
10. Have you peformed a visual inspection late at night with the room pitch black, with red film placed over a fashlight and checking the polyps in question for latenight irritation or predators?
11. Any fish nipping at your polyps?
12. Any inverts, it so, what type and how many?
13. View this link for future reference, I hope it helps.

If you have already performed a dip, just curious how it went and if they are doing any better. Good luck and I hope they pulled through for you.
