Fresh water dips for flukes. note:Can be hard on some fish so I use Prazi instead. At 78.8F and 35 salinity, you dip for 3 to 5 min in fresh water on day 1 of treatment. Then in 7 days you repeat. Their calculator changes times based on temp and salinity. Taken from

From other sources I read Prazi works on flukes upon contact. So I think 24 hours should be more than enough time. However, on fish with very thick slime coats, it may not fully penetrate the coating. Thus allowing some flukes to persist.
In conclusion TTM with (Prazi - 7 days apart) should be enough. Unless you see something else
