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 a combination chosen from below:

SCENARIO A: Planted pond, Aquascape Filtration, Water under 80o DF: Use Interpet, Paracide Green, ProForm C or other 37% Formalin / Malachite Green solution according to label instructions or to accomplish 25 ppm. With Formalin Malachite Green 37% solution, 25 ppm is had by using 1 cc per ten US gallons every day for five days. With Aquascape filtration, you don't have to do water changes if the pond is under 80o DF. These ponds have high aeration (excellent air pump) and an organic load that handily breaks down Formalin before it hurts the fish. Watch for signs of low oxygen if water is warm. Do not use in winter water below 45o F. Safe for plants, Goldfish and Koi. Verify parasite clearance with microscopy.

SCENARIO B: Planted pond, no gravel or signficant organic debris in substrate, water under 80 DF: Shotgun treatment with Praziquantel and Potassium permanganate. Dose daily with one level teaspoon of Potassium permanganate per six hundred US gallons for five days. After the fifth treatment, do a forty percent water change, decolorize the rest of the PP with 3% hydrogen peroxide and then deploy Praziquantel. Safe for plants, Koi & Goldfish. Verify parasite clearance with microscopy.

SCENARIO D: UN-planted pond, Aquascape Filtration, water under 80 DF: Deploy salt at 0.6% and Praziquantel. Safe for Koi but will kill all Goldfish. Verify parasite clearance with microscopy.

SCENARIO E: UN-planted pond, no gravel or significant organic debris in substrate, water under 80 DF: Deploy salt to 0.6% and deploy Praziquantel on day one and again on day four. Safe for Goldfish and Koi. Verify parasite clearance with microscopy.

SCENARIO F: UN-planted or planted ponds in very COLD weather: Dose daily with one level teaspoon of Potassium permanganate per six hundred US gallons for five days. After the fifth treatment, do a forty percent water change, decolorize the rest of the PP with 3% hydrogen peroxide and then deploy Praziquantel. Safe for cold water, plants, Koi and Goldfish. Verify parasite clearance with microscopy.

SCENARIO G: Planted ponds in very HOT weather: You need to cool the pond down with daily water changes. These water changes are required when using Formalin in warm water anyway. So do a fairly major water change to begin with in order to cool the pond, and provide what shade you can to the pond. Use Interpet, Paracide Green, ProForm C or other 37% Formalin / Malachite Green solution according to label instructions or to accomplish 25 ppm. NOTE: With Formalin Malachite Green 37% solution, 25 ppm is had by using 1 cc per ten US gallons every day for five days. I highly recommend that in warm water (over eighty degrees Fahrenheit) that you would only leave the Formalin/Malachite in the pond for 120 minutes THEN do a major 50% water change. Further cooling down the pond and removing the Formalin. Verify parasite clearance with microscopy.
