Salt does not kill the parasites on the koi, because adding salt to the water only increases the osmotic pressure of the water, allowing the koi to absorb less water. This prevents parasites, but does not kill them. In order to kill the parasites on Koi, it is better to use drugs. Before using drugs, we should first determine what parasites are, and then choose the appropriate drugs. Some parasites, such as anchor head fleas, cannot be killed by drugs alone. They need to be cleaned up with tweezers and then bathed with trichlorfon.
1. Can salt kill the parasites
on Koi? Salt can't kill all the parasites on Koi. Although they have the function of sterilization and disinfection, adding salt is to increase the osmotic pressure of water, not to kill the parasites directly, and putting less salt has little effect on the parasites. Too much salt will cause harm to the body of Koi, so it is better to use drugs to kill parasites after Koi is infected with parasites. As mentioned
above, it is impossible to use salt to kill all the parasites on Koi carp, so we need to rely on drugs to treat them. Before medication, the breeder needs to determine what parasite the koi is infected with, because different parasites are treated differently. Parasites like anchor-head fleas cannot be completely killed by drugs alone. Breeders need to clean up the parasites with tweezers first, and then mix trichlorfon in proportion to take a medicated bath for the sick fish. The medicated bath will be effective in about 3-5 days.
In the later feeding process, regular disinfection should be carried out, and the filtration system, especially biochemical filtration, should be strengthened. In this way, the nitrifying bacteria in the fish tank will increase. Even if the koi has a small amount of bacteria or parasites, it can recover by itself depending on the ecological balance in the water.
