Wow, not sure what to suggest. I would treat as if it were ick, maybe its a different strain? Formalin will kill any external parasites (ick??) however it does cause a bit of gill damage (so use lots of aeration while using, the gills will heal fairly quickly after the treatment but its good to aerate well). Its not too bad to use although it can be pretty noxious stuff. FW treatment and hypo might be your best bet at this point but it sounds like a few of the fish don't have a lot of time to spare.
I dunno, I'd want to at least do something. Just not sure what. You can always start with the FW and hypo and if that doesn't work move to a more aggressive treatment.
