I came across Minh's thread a little less then a week ago by accident. As it turns out I hade the same problem as what he had described.
Here is a thread that I started which described my problem.

Minh confirmed through email that it looked the same as what he went through so I decided to dip my infected clams. (FW in same temp for 30mins).
Here are some pics after the dipping. They didn't extend as much as before; but they are improving from the looks of it. A third (the smallest) clam which is shown at the pbase site recovered right away (strange since he was dipped with the blackish one)
