I want to be perfectly clear on the directions...
Are you saying to dose for 5-7 day or, dose once every 5-7 days?
Water change out on day 5?
Repeat until no signs of flukes are present?


Because flukes are naturally clear a visual confirmation is nearly impossible. Confirmation of flukes can be obtained via a freshwater dip. After 3-5 minutes the fluke will become opaque and dislodge from the fish. Although helpful, it is not a necessity, to identify the fluke’s family to aid in treatment. A microscope can confirm a species, however, Neobenedenia, can be seen with the naked eye.

1. Praziquantel or Prazipro – There have been several studies demonstrating various applications of Prazi. For practicality only a couple is listed. Prazi does not kill flukes. It induces uncontrollable spasms to where the fluke dislodges from the fish and continues to spasm. Studies have shown that after 10 hours the fluke dies. Prazi is very gentle on fish to the point it can be overdosed with no ill effects. The exception is wrasses. They are able to handle the 2.5 mg dosage but anything over that can be detrimental. It has also been reported that Prazi is safe to use in a reef aquarium with minimal casualties such as feathers and other worms. A word of caution: Prazi can act as an appetite suppressant. It also depletes the oxygen in the tank so be sure to fully aerate during treatment.
]a. The most common method of dosing Prazi is dosing 2.5 mg for 5-7 days, then performing a water change, and finally redosing the full amount for another 5-7 days. A third and fourth dose may be necessary. Prazipro is reportedly (via personal communication with Hikari) “out of the water” 72 hours after the initial dose. However, once treatment is concluded it is recommended to do a large water change and add carbon to remove all traces of Prazi[/U].
b. Another method is to do (2) 40 hour baths 48 hours apart in 5 mg/L Prazi.
NOTE: In 2013 research done

Prazipro directions state 2.5mg/l, "A single treatment lasting 5-7 days is normally sufficient. Repeat as necessary, but no more than once every 3 to 5 days"

from what we know of the lifecycle a 2nd dosage is necessary.

Does anyone know when the flukes lay their eggs, do you they lay them on the fish, rocks or the on the aquarium glass?

eggs are dropped, wherever they land. for 2-7 days (or 4-6, depending on source of info) they'll hatch after that and they have 2-3 days to find a fish or die. lower temps extend how long the eggs develop before hatching.
