1. Is it OK to add edible salt to koi fish tank It is not possible to add edible salt to koi fish tank. Salt is usually added to the fish tank, which is coarse salt. Other salts may be harmful to fish. Moreover, it is worth mentioning that as long as the fish are healthy, they don't need salt, and they only need salt when they are sick. Salt is usually put to change the osmotic pressure of water body, which can reduce the water penetrating into fish, help prevent bacterial invasion, and reduce the burden on kidneys.
2. What should we pay attention to when adding salt to koi fish jar1. Pay attention to concentration: The first thing to pay attention to when adding salt is concentration, which varies according to different needs. If it is the early stage of the disease, the concentration should be controlled between 3% and 5%. If there is ulceration on the body surface, it needs to be soaked in salt water, and the concentration will rise to about 1%.
2. Pay attention to time: The time for washing fish with different concentrations of salt water is different. If it is 3/1000 salt water, it is no problem to raise fish for a long time, and then gradually change into clear water after the fish recovers. If it is 1% salt water, the soaking time must be controlled within 30 minutes.
3. Pay attention to fish: The higher the concentration of salt water, the greater the side effects on fish. Therefore, if fish is soaked in more than 1% salt water, it must be observed at all times. If discomfort is found, it should be fished out immediately to avoid death.
