1/2 tsp per 10 gal. of PP is the dose amount. Treatment takes 4 days,
but reinfection is high. Because it is *not* a medication or
antibiotic, with Flex. disease, most or all the fish will likely be
dead by the end of the second day. PP will raise the pH, and the tanks
temp is to warm - two things that speeds up the killing time when it
comes to Flex. disease. Antibiotics on the other hand, kills the
bacteria for the most part, the 1st. day. A 10 day treatment is tipical
with antibiotics, well over twice as long as really needed as for as
treating the fish. The extra time is to cover your behind, making sure
not to end up with a resistance bacteria/disease. ........ Frank
