Stone can be placed in the fish tank, and pebbles are the main ones. This kind of Stone is round, has no edges and corners, will not hurt fish, and is not easy to hide some harmful bacteria, and can also provide an attached environment for nitrifying bacteria. It should be noted that Stone must be disinfected before putting it into the fish tank, and then cleaned, so as not to pose a threat to the health of fish.

1. Beauty: The first advantage of putting Stone in the fish tank is beauty, which increases ornamental value. Although fish farming in bare tanks is also good, fish will appear monotonous without the foil of scenery. Therefore, some landscaping stones can be placed in the tank, which can make the fish tank look more like a wild environment.

2. Culture of bacteria: Culture of bacteria is needed in fish culture, in which nitrifying bacteria need to attach something to survive and cannot float in water all the time. With Stone, it can provide a place for its growth and reproduction. This bacterium has a great effect, which can convert ammonia nitrogen in water into nitrate, which is very helpful to the health of fish.

3. Water purification: Stone can also purify water, because impurities and excrement in water will fall to the bottom. Without Stone, it is easy to move with the water flow, causing the water body to become turbid. With Stone, it can be stabilized at the bottom without being everywhere.
