for RB, i'm going to treat the whole tank.
for AEFW, thus far, I've only dipped the 6 or 7 frags I mentioned. When I get the levamisole, I'll decide then if I want to dip and QT just those or pull out all of them - I really don't want to, though.
Mike - there are several methods. I haven't read too much on it yet, but from what I've read so far:
Dip in TMPCC and/or Revive cleanser
Some use fluke tabs
Some use Levamisole
I think some use Lugol's solution?
Then you keep the dipped frags in a QT tank for 6 weeks I think. The rationale for taking out ALL frags is to eliminate any food source for the AEFW. They thus die off just in case the dip didn't get them, or missed scraping off some eggs.
