The turbid water in goldfish bowl is usually caused by not changing water frequently or feeding too much, so the solution is to change water regularly and reduce feeding. Changing water is a must for fish farming, and raising goldfish is no exception. Usually, if the water quality is maintained poorly, it should be changed once every three to five days, and if it is maintained well, it can be changed once a week or two. Feeding should be regular and quantitative, and it can be fed three times a day, and it is advisable to ensure that the fish can be eaten within 5 minutes each time.

1. Filtration: To improve water quality, the best way is to filter. Fish tanks are generally equipped with filters, which can generate water flow and let the water flow filter the tank, thus filtering out impurities. Moreover, there is a nitrification system, which can slow down the aging of water quality. If the filtering effect is not good, it is necessary to pay attention to cleaning the filter cotton or replacing the equipment with higher power.

2. Change water: Fish farming must change water. If you don't change water for a long time, even if the water quality is clear, it will contain a lot of ammonia nitrogen, which will affect the health of fish. Usually, according to the deterioration of water quality, it should be changed every 3-5 days. If the water quality is maintained well, it can be changed once every 7-10 days, and one quarter of it can be changed every time.

3. Cleaning up: The poor water quality is mainly due to some pollutants in the water. As long as they are cleaned up, the deterioration of the water body can be slowed down. Most of the pollutants are residual bait and fish droppings, so if you want to improve the water quality, it is also an option to reduce feeding, but this will affect the growth of fish.
