When raising Arowana, the water quality is a very important problem. If they want to grow well, they need to keep the water clean. To keep the water clean, it is necessary to control the frequency of water change. Generally, they are changed once every 3-4 days, but the silver arowana is relatively large, and it takes more time to change water frequently.

Most breeders will put a filter device in the fish tank to clean up the excrement, unfinished food and other substances of silver arowana, which can prolong the water change time. Usually change their water once every 1-2 weeks. If it is winter, their metabolism will slow down, so it is ok to change their water once every half month.

Changing the water of fish tank is a process that every breeder must go through. There are many suitable waters for their survival, such as rivers and lakes, tap water, well water and so on. Among them, tap water is liked by the majority of breeders because of its clean and easy access. Become the most commonly used water. However, tap water contains chlorine gas, so it is necessary to expose them to the sun for a period of time to remove chlorine gas from water before use, so as to avoid harming silver arowana.

When changing water, first receive about a quarter as much tap water as the water in the fish tank. Then measure the temperature, PH and other factors of the water in the original fish tank. Then adjust the tap water to make it similar to the water in the original fish tank. Finally, take out the water in the original fish tank and replace it with new water.
