Formalin not working. Does hypo kill brooklynella?

[shelburn61]

I'm having a hard time finding definitive info on brooklynella. I've been using formalin, the standard treatment, without very good results. I'm hoping hypo will kill brook as it does other protozoans?

I bought a swallowtail angel a few weeks back. It developed soft, white, fuzzy patches on the fins. Seems to be (from what I've read) brooklynella so I did a 1hr formalin bath at 20drops/gal and spots seemed to get better. Spots returned in quarantine. Repeated formalin bath and also added formalin to quarantine tank at 1 drop/gallon.

Spots seemed mostly unaffected so I've gone to hypo. The fish has eaten through all of this. She has looked very stressed at times, but overall health doesn't seem too severely affected yet. Spots only appear on fins. Best pics I could get:

(This is not lymphocystis)

Here was a post from a very respected Agriculturist at Drs. Foster and Smith about Brook treating:

I think your fish has Lymphocystis not brook. Formalin will do nothing for this condition. It is viral in nature. Good nutrition should help it go away. By the way hypo will not kill brook.

Picture is not that clear .. but I would agree that does not appear to be Brooklynella. Lympho is a possibility .. if so, no med is going to help. Other possibilities include fungus or even bacterial but pic's not clear enough to really identify.
