The correct way to change the water for tropical fish, how often to change the water for tropical fi

It's easy and quick to change the water in winter!

The frequency and timing of water changes for tropical fish depend on the feeding conditions and the species of tropical fish. If the aquarium filtration system is in place, the number of fish is appropriate, and the aquarium is well managed, a small amount of water can be changed every week, and then all the water can be changed from a few months to half a year or 1 year. However, if it is not well managed, it is necessary to increase the number of water changes.

If the water quality is not seriously deteriorated or the fish are infected with infectious diseases, it is better not to use all the water changes, because it is difficult for tropical ornamental fish to adapt to sudden changes in water quality.

The water in the small fish tank is mixed quickly, and it needs to be changed frequently, about once every 5-6 days. In addition, each time you change the water for 1 3, the water quality is kept fresh without changing the original growth environment.

For feeding, in general, 1 or 2 times a day is fine. It is best to feed at the same hour. If you want to keep several tropical fish at the same time, you can feed them twice a day, once in the morning and once in the evening.

Tropical fish can only have a good appetite if they grow in the right environment. So, in addition to the food being delicious, it is also important to create an environment that is suitable for them to grow. Factors such as low dissolved oxygen, inappropriate water temperature, and deterioration of water quality can affect the appetite of fish.

When changing the water for tropical fish, it is best to dry the tap water in the sun for two days in advance, then suck out the garbage at the bottom of the tank, replace one-third of the water in the tank with the dried tap water, sprinkle a little coarse salt or sea salt, and then replace one-third of the water in the tank every 7 days.

Many friends who raise tropical fish should want to know what is the correct way to change the water of tropical fish. In general, tropical fish are raised at home and choose to use tap water, but before changing the water in the fish tank, it is best to pack the tap water and let it dry in the sun.

Because tap water contains bleaching powder or other chemicals, if it is poured directly into the fish tank, it is likely to cause harm to the fish and even lead to the death of the fish in the fish tank.

After that, put the suction hose into the bottom of the fish tank, suck out the feces and other garbage at the bottom of the tank, and pump out about one-third of the water, add the dried tap water, sprinkle a little sea salt or coarse salt, and then replace one-third of the water in the fish tank once a week.

1. Take a bucket of tap water first, put it in the sun for two days to remove chlorine gas (if it is poured directly in the fish tank, it is easy to cause the death of the fish), if you are too lazy to move to the sun, put it in the room for two or three days, it is not recommended to use chlorinated chemicals such as Yulebao, after all, there will be toxic residues for long-term use, and natural evaporation is the best.

2. When the drying time is almost up, put some sea salt or coarse salt into the water, which has a disinfection effect and can also promote the appetite of the fish.

3. Start to change the water, first use a simple toilet to suck the fish feces and residual feed out of the Chasheng shed, and pump out 1 3 water.

4. Finally, slowly pour the prepared fresh water into the fish tank and mix it with the remaining water, so as to ensure a good water quality environment for the fish and make the fish live longer.

1. Tropical fish water quality conditioner

Adding water conditioners to the tanks of tropical fish can eliminate ammonia nitrogen, reduce nitrification, etc., and maintain stable water quality. At the same time, some water conditioners can also add some beneficial trace elements to improve the immunity of fish and promote growth.

The use of water conditioner is usually to pour an appropriate amount into the water tank, add it according to the proportion indicated in the instructions, and be careful not to overuse.

2. Seaweed powder

Seaweed powder is rich in protein, vitamins and trace elements that contribute to the growth, health and beauty of tropical fish. The method of use is to sprinkle an appropriate amount of seaweed powder in the fish tank and let it settle naturally. Seaweed powder can be used as a food for tropical fish or as an additive to enhance the growth of microorganisms in the water.

3. Plant filter

The plant filter is a natural filtration method that uses plants in the water for biological purification, converting harmful substances in the water into beneficial phytonutrients, thus maintaining the stability of water quality. At the same time, the plant filter can increase the ornamentality of the fish tank and make the life of tropical fish more interesting.

Plant filters require technology and inputs to set up, but they are a good choice for long-term farmed tropical fish.

4. Hidden number of mineral water

For some tropical fish farmed in a home environment, mineral water can be considered for re-refilling. Compared with tap water, the hardness and salinity contained in mineral water are more suitable for the growth and development of tropical fish.

When using mineral water, it is necessary to pay attention to the fact that you must choose a pure, sterile brand, add the right amount of mineral water to the tank, and do not forget to add the right amount of water quality conditioner.

1. Trap the water in advance: To change the water for tropical fish, you must first trap the water in advance. By drying and other methods, the chlorine inside can be volatilized cleanly.

2. Pumping and water filling: first pump out the old water in the tank, and then slowly mix the prepared new water from the tank wall.

3. Water change cycle: Usually there is no fixed cycle for water change, because the size of the fish tank and the density of feeding are different.

4. Precautions: Change the water to avoid changes in water temperature.
