The most common way to change the water in an aquarium is to do a partial water change, in which a portion of the breeding water is used in a special substrate cleaner to remove dirt that has accumulated on the gravel along with the old water. This method does not require any manual labor such as moving the aquarium.

Remove moss from the glass surface of the aquarium using a special moss removal cloth to avoid scattering it as much as possible.
If too much dirt accumulates on the filter media, the filtration capacity may decrease. Gently wash away dirt with breeding water regularly.
