Snip:
The idea is not to kill all the parasites, actually that is not really
possible anyway. It is to drop the level and slow em down to where the
fish can
fight the disease themselves while providing as pristine water conditions
as
possible. both formalin and PP will do this and be gone in 4-12 hours.

Agreed, but they are certainly more stressful on the fish, who are already
stressed, than using .3% salt for salt sensitive organisms!

That being said, I use PP and formalin when indicated, without issue.
