Hey Kacey,
Thats what I read about PP and also read that only short baths are effective as extended is too hard to control the correct amount needed to kill flukes.
I do a similar PraziPro treatment as you accept I do a full dose after the 50% daily WC during the 3 days on.
I have a tank of stunted discus that are my hero discus that I would like to try Supaverm on when I can acquire it. Obviously I would have to wait until they get gill flukes and even then I would need to scope them to gaurantee it's effectiveness.
