Ceramsite sand is currently the most commonly used bottom sand for fish tanks. It is especially suitable for raising small and medium-sized fish such as guppies and mini parrots. The advantage of laying this kind of sand is that it will not cause turbidity in the water body. At the same time, this kind of sand can also adjust the hardness of water, which is helpful to the health of fish. Ceramsite sand can be planted with aquatic plants, but because it does not contain any fertilizer, it needs to add nutrient solution and so on. In addition, because of the dark color of this sand, it often causes the fish's body color to darken.
The big difference between cosmetic sand and ceramsite sand is the color. The color of cosmetic sand is white, which is more suitable for laying in tanks of fish such as cichlids in Sanhu. In addition to being used as bed sand, it can also be used as a waterfall landscape. However, due to its own color is too white, there are certain shortcomings, that is, fish excrement in the above will become particularly obvious, and because it is very small, so the cleaning time is also more troublesome.
If you put some sunken wood or big leaf water banyan in the fish tank, then it is recommended to spread rain forest sand. This kind of sand is also very small, fish manure is not easy to bury, cleaning up is more convenient. However, this kind of sand collocation is more limited, generally only suitable for South American series of fish, such as brontosaurus, many common tropical fish are not suitable.
