Not sure what those packets are, but if you dip (or even bath), you will only temporarily attack the trophonts on the fish. Then, you'd put them right back into the infested tank. More stressed out than they were before because of the dip. They've seen that Ich trophonts sometimes don't release from a fish's body even after 24 hours in freshwater (of course long after the fish itself died). Freshwater is thought to be one of the quickest ways to kill Ich (osmotic pressure changes causes most marine organisms with exoskeleton to explode).
Did the 2 dead fish die in the tank? Have to consider that this caused the Ich trophonts in the tank to go up quite a bit, as their bodies were covered in it, now the Ich is searching for a new live host.
Your tank is infested, I would act quick and jump to a full on display tank treatment of whatever you decide and wouldn't bother with any dips or baths, or taking fish out unless it is to get them in QT. My $.02.
Also, you want to turn off your skimmer and pull GFO/carbon for any treatment you try.
Some believe that unless you have massive UV capability for high flow, you're not putting a big dent in an infestation (whereas UV may help cut down Ich if it is at lower but sustained level in the tank).
