Why you should clean your betta fish tank?

Firstly, you need to clean the tank regularly to control the nitrogen cycle. The mechanism in which ammonia is converted by bacteria to nitrite and then to nitrate is the nitrogen cycle. Both ammonia and nitrite are poisonous to fish, so it is important to have colonies of bacteria in your fish tank to turn harmful compounds into nitrate. Nitrates are much less toxic to fish, and frequent water changes will remove them.

Secondly, you need to clean your tank periodically to extract dissolved organic particulate matter. Also, the water itself contains a lot of minerals and nutrients that Betta requires. The water is, however, preserved, and there is no new way of reproducing water. But you should change the water while you’re washing the tank.
