Flukes are classified as trematodes and among the largest of the microscopic parasites. They are worm shaped with a mouth at one end and a suction cup shaped foot at the other end. The foot has several claw like anchors called haptens. They use these haptens to puncture the skin of the fish so they can hold on while feeding on the slime coat. As they puncture the protective skin layer of the fish they often introduce Aeromonas or Pseudomonas bacteria thereby causing an outbreak of bacterial soars on the fish. In large numbers they can kill fish even without the bacteria issue.
Supaverm is safe for use on koi only. It will kill goldfish! It is believed to remain in the water after use for up to one month. It will not harm the filter media. Remember to shake the bottle well before use. Treat the pond with 1 ml per 100 gallons. Do not perform any water changes for at least 10 days. Supaverm has been shown to be much more effective when used with a salt level of .3% or higher. For that reason we highly recommend using it with salt. If there are plants in the pond and the use of salt is not possible, we recommend treating a second time 5 days later. It is not necessary to do a water change after using Supaverm.
