Dosage of praziquantel powder?

Hi I am in the process of treating 400 gallons of water for flukes. I have been told two different dosages which vary greatly one is 7.6mg per gallon and the other is 1/4 teaspoon per 40 gallons. If I am doing my math correctly the first one equals 3 grams and the second one equals 10 grams. Could anyone shed some light on this please? Thanks I appreciate it. Tom

Dosage of praziquantel powder?

Where did you get it from? Natnl Fish Pharmaceuticals says 1/4 tsp per 40 gallons and I believe Dmorty had a book stating 1.5mg/l. Humble tested prazi at 2mg/l with success but recommends 2.5mg/l.

At 2.5mg/l it is 3.785 grams for 400 gallons. At a 1/4 tsp per 40 gallons you are getting 10 grams using the sugar conversion. Sugar more than likely weighs a lot more than prazi. I would bet the equations come out to be about the same if you were to weigh 1/4 tsp. Knowing who the manufacturer is will help figure this out.

2.5mg/L is a starting point. I have dosed it at 5mg/L with no issues when dealing with Prazi resistant flukes (still didn't kill the flukes)

Ok yeah I may be dealing with some tough flukes too because I have done 2 doses and it seems like they are lingering around. I wish I could dip them but they are really hard to catch and I don't want to stress them out too much. Any other ideas? Thanks

You could do hypo. 15ppt for 5 days will eliminate eggs, juveniles, and adults.

I have gone away from Praziquantel because of that. I use Mardel Clout now instead
