The reasons why the water in the fish tank turns white:

1. The water quality is aging. Regardless of whether there is a filtration device in the fish tank, it will age over time and the water needs to be changed immediately.

2. Feed a large amount. Feeding too much food can also cause the water to become white and turbid.

3. Raise too many fish. Adding new fish to the tank without restriction will accelerate the deterioration of the water body and cause the water to turn white.

4. Excessive addition of water quality treatment agent. Adding too much water treatment agent, such as water purifier, is likely to cause the water in the fish tank to turn white.

5. There are many particles and impurities. When a newly purchased fish tank is opened, or when the filter material is replaced, some particulate impurities may be emitted into the water, causing the water to turn white.

Solutions to the white water in the fish tank:

1. Purchase a good quality fish tank and filter material. You can buy good quality fish tanks and filter materials in regular stores. The newly purchased fish tank needs to rest for a period of time and be disinfected before use.

2. Add water treatment agent carefully. In the process of raising fish, it is best not to add some chemicals rashly. Even if it must be added, the dosage needs to be strictly controlled.

3. Establish a filtering system. It is best to establish a good filtration system in the fish tank, change the water regularly, and clean the fish tank.
