How long can the tap water be kept for fish farming?

I believe experienced friends all know that "fish culture first water" this truth, after all, the water environment is the most important factor. Tap water is the most convenient source of water in the city, so how long can tap water be kept for fish farming?

Fish can be raised after the fresh water is exposed to the sun for 24 hours. Tap water mainly contains chlorine, which is easy to harm schools of fish in the water and cause fish casualties. It is usually kept for about three days to reduce the chlorine content in the water, so it is better to keep fish in tap water for three days. And solar exposure can dechlorinate, so it can speed up the process.

Fish farming also needs to pay attention to:

1. The fish tank should be sterilized before use (brush it with high concentration of potassium permanganate water, then soak the fish tank with low concentration potassium permanganate water for about a day, and salt water can also be used).

2. Choosing fish is also very important. Sometimes the fish that choose to go home have already got sick. (this requires a lot of experience on weekdays.)

3. Take the new fish home. At this time, you should notice that the water temperature in your fish tank has reached the temperature at which your small fish are suitable for growth (tropical fish 26 degrees plus or minus 1 degrees is more suitable, goldfish koi and other fish are generally 24 degrees plus or minus 1 degrees, but this is not an absolute value).

Do not open the bag, put the bag into the fish tank, float for 10 to 20 minutes, and then pour the fish into the tank. Do not feed the fish for three days. Then feed the fish twice a day, and it is best to eat the small fish within five minutes each time.

4. Change water, change about 1/5 water every day without filtration aeration system, and change 1/3 or 1/2 water in about three days with filtration aeration system. Be careful not to use the tap water that just came out. After the tap water is picked up, it is best to put it for two or three days, and then change it for the small fish.

Because tap water contains a lot of substances harmful to fish. Another is to pay attention to the water temperature control of the change of water, the new water and the water in the original tank, the water temperature should not be plus or minus 1 degree.

5. Pay attention to the problem of oxygen consumption of small fish. if there are more fish, you have to increase the oxygen pump to do oxygen.

6. After the fish is sick, go to the fish shop in time to consult the medication. Consult a few more companies, one is to increase experience, and the other is to prevent being deceived. )
