By PP, I assume you mean PraziPro.

It had no effect at all on any of my plants, including the algae.

I dose X3 in the spring and once in the fall.

PP - Potassium permanganate. If you fully nuke the pond then yes...it will clean it out good.

What did you end up doing for the gill flukes? If the gills looked really bad, it may have had bacterial gill disease.

How are your fish now??

I did a prazi routine 2x, 7 days each. I was going to get them in the pond and then maybe do one more prazi treatment out there but the weather has been so horribly cold and wet I havent gotten them out. I decided I just do NOT want to wreck my algae/bacteria ecosystem by using PP on it.

I fed them food soaked in prazi for7 days because I was paranoid about tape worms - havent seen any white pieces lately so who knows.

The remaining fish look fine, better than they have in years. The ones with white, their white is much whiter - they probably had body flukes as well. They actually started looking better that very same night I started treatment- that was the day I saw them ALL at the surface with their gills flapping - I did a radical water change of about 90% and even then they seemed better, then added the prazi, and the next morning they were swimming around seemingly happy and normal. WHEW....

I am still seeing the occasional long threadlike, wormlike thing (clear) so who knows. Someone may have calmarus (sp????) worms... which requires a different treatment).

What I find kind of frustrating is that with flukes, they take much longer to hatch at cold temps rather than at warm temps. No where could I find any kind of info about how long the intervals might be at different temperatures. IE if my water temps are 50, then what would the hatching interval be? I treated 7 days apart, but it could be that I still missed the next batch of eggs hatching. They might hatch out at 65 and then I'll have a mess all over again.

If anyone's looking for a science project, that would be a good one to do!

I literally just finished FIVE rounds of prazi 5-7 days apart. Gill flukes are HARD to get rid of!

Ughhhh.... that's what I was afraid of. How do you know if you have gotten rid of them????

I see some fish mouthing again - like they have mouth flukes. Either that or they're begging for food!

Scraping and scoping...and even then you can miss them. That's why I decided to mercilessly prazi them to death. lol If I were you...I'd do a few more rounds, 5 days apart.

What does "mouthing" mean? Yawning type of motion?

That thing they do, opening and closing mouth repeatedly. May be begging for food though. Those dang fish can sense me coming from a long ways away.
