I have used this product several times for gill flukes as my fish were 'flashing' a lot. The Nitrates and Nitrites levels in my tank were near zero and I do regular water changes so combined with this product the flashing should stop, which it does for a day or so and then it resumes. Despite following the instructions to the letter I find the product doesn't cure the problem, just postpones it. The most efficient cure for flukes I have since found is Tremezol.
