How much salt does it take to raise goldfish in a fish tank?

If you keep goldfish, you need to put 2~3 spoonfuls of salt in a washbasin. Less salt has no effect. When the goldfish is in a bad state, adding more salt can cure the disease. \x0d\ But too much salt will kill small goldfish and pose a great threat to their health. At the same time, under the same conditions, the growth of nitrifying bacteria will be inhibited in salt water, which is not conducive to the decomposition of harmful substances in water by nitrifying bacteria. Instead of adding salt to inhibit the growth of bacteria, it is better to put less fish in a jar and strengthen filtration. \x0d\ You should pay attention to the following aspects when raising goldfish: the water quality should be good, the light and temperature should be suitable for the growth of fish, and the fish food should be guaranteed and kept away from toxic substances. \x0d\ If you want to raise goldfish well, you must start with preparation. 1 airing water should be dried in the sun for 3-7 days before it can be used, but hydroponics for 6-7 days is the best, and generally it is more appropriate to add two thousandths of sea salt. Don't feed goldfish more, eat less and eat more meals, twice a day is better, and it is better to feed them for 3-5 minutes. Save water for 3-5 days when changing water, accounting for a quarter of the total water consumption. I hope my answer is helpful to you.
