Whole books could (and have been) be written on parasites in Koi but for simplicity we could suggest some shotgun remedies that we have found to be effective. I will reference various medications in this and future sections, to give you direction. It is your responsibility to learn how to use these medicines SPECIFICALLY and I recommend that you read all you can by qualified, experienced people. I wrote a whole book on this stuff, called “Koi Health & Disease” by Dr. Erik Johnson. (That’s me) In most ponds, a person could clear most significant parasitism with the treatment below:

Treatment: Praziquantel and TERMINATE. Attention: Always increase the aeration in your pond when using TERMINATE 

Safe for plants, Koi & Goldfish. Verify parasite clearance with microscopy.
