is like fluff on the wall of the fish tank? What is like fluff on the wall of the fish tank is a bacterial membrane. The biofilm is usually produced by some beneficial bacteria, which are almost harmless to the fish tank and fish, and will not last too long, until the nitrification system is established, it will slowly disappear. However, there is a bacterial film in the fish tank, which is very ornamental and gives people a look that is not very clean, so it can be cleaned up in some ways.
the biofilm 1. Manual cleaning: The most direct way to clean the biofilm is manual cleaning. Take out the stone, sunken wood and other things with bacterial membrane, then brush them off, then rinse them with clean water, and then put them back into the fish tank, preferably with the original tank water, so that they are safer after washing.
2, fish cleaning: If you do not want to manually clean, you can also raise some fish, some fish will eat the membrane, such as small monkeys, flying foxes, guppies, panda rats and so on. Also can raise black shell shrimp, if be cold water fish, put goby or suck loach also can, they have the characteristic that cleans up bacterium film.
3. Natural decomposition: As mentioned above, the biofilm will decompose naturally after a period of time. Because the nitrification system in the tank has been established, the substances decomposed by organic matter will be transformed by nitrifying bacteria, and the bacteria in the biofilm will lose their source of nutrition, so they will disappear slowly.
