That’s what I do. I used to throw some iodine and declor in a bowl but now I just dip them in tap water. I wouldn't do this with expensive corals, but regular ole zoas get SA aqua. However, I don’t dip for 10 minutes like Bird, only because I have watched nudis and pods die in a minute or two and figured that’s long enough…but he has a lot more experience than me.

Only other thing that I’ve came across with zoas are light changes which can really affect them. I’ve had some disappear practically overnight, and I believe it was due to my LED’s high intensity.
