I have had issues with flukes in my tank for a while. The fish are shaking and flashing. It doesn't apear to be ich as I had copper ran for a while. When i lower the salt level to 1.009 it seems to help then with evaparotion it seems the flukes come back. I have prazipro in there now and now the fish are breathing really hard. I also seem to have an algae bloom. The Ph is around 7.8. I tried prazipro before and it didn't help these types of flukes. My question how low can I lower the salt level? These are stubborn flukes and I want to run hyposalinity for a month. Or if there are any other suggestions.
