Before I even start to explain, I just want to say that all my water parameters are fine except for phosphate being a little high. OK, so, my fish were flashing, and after a scrape, I discovered skin fluke. I have been treating my pond for flukes for over four weeks now. I started out with Aqua Prazzi and retreated after the third day in case of any eggs. The fish continued to flash. I gave them a second treatment, same thing after the third day another treatment so in total for treatments of Aqua Prazzi. The fish continued to flash. I did a second scrape, I didn't find anything, but I figured it was still fluke. So then I tried fluke M. Seven day treatment. The fish continue to flash. And then another treatment of fluke M. This treatment will end tomorrow and the fish continue to flash. They don't slow down. It seems like they're flashing even more. I did another scrape. I found absolutely nothing. PH is fine. No ammonia, no nitrites. I really don't know what else to do. Does anybody have any other suggestions?
