I dipped the frag in fresh water, but the water was kinda cold. I think that shocked the frag to death. It was barfing all over itself, and I was worried about it bothering my other frags, so I tossed it. It was a freebie, but I was dissapointed to lose it. In retrospect I should have been more patient on a number of levels:
(1) Let the water warm up more
(2) Let the frag try and recover longer
I have a different frag that came with a few dead heads. My turbo went over it, cleaned of the dead heads into clean stumps and now one of them is openeing again. Had I know they could be so resilient, I mught have left the other frag in a bit longer to see if it would make it. I really doubt it would have, it looked REALLY bad. Seemed like some of the under structire was showing through.
I'll get some iodine dip to have around in case something else comes up. Thanks again for the help weet!
The next time you have to do a FW dip, take around a cup of distilled or RO water and put it in a bag (I use ziploc) and float it in the tank for 15 mins. This will get the water to the same temp as your tank and will prevent the temp shock you described.
If polyps are so bad off that they have partially dissolved, I doubt you could save them.
However, if they are intact but just unhappy, it's worth your time to try to save them.
I usually start with an iodine dip.
If the situation is really severe or lugol's iodine has been ineffective, use Furan-2.
I try to always keep both on hand.
