I don't think you understood the situation correctly, or what comment I was referring to.Flow and light does matter as it can shock the coral. The coral has been dipped in coral RX which is one of the best on the market. . . Why would he turn around and iodine dip it and stress the coral more and then shove it under bright light?
A dip will stress a coral before acclimation does.
First - Coral Rx while it is a great dip, it is mostly useful against pests and can be sometimes hard on some corals.
Second of all - The tissue receded the day after it was introduced to the system, hence why an Iodine dip is advised now.
Third - I explicitly said high PAR isn't a good idea for a stressed coral, not otherwise.
Forth - Some flow is needed, and I mentioned this. Lack of flow will not make the tissue receded by itself overnight.
