It is better to lay ceramsite in the fish tank, because there is no nutrient in the sand, and some aquatic plants can be planted with ceramsite. Of course, the choice of bottom sand is mainly related to fish, according to different breeding varieties, to choose the appropriate bottom sand. It should be noted that although the bottom sand has a certain decorative effect, but the fish excrement will remain at the bottom of the sand, cleaning up a certain amount of trouble, if the filtration is not good, it will also lead to deterioration of the water body.
1. Ceramsite: Ceramsite is the commonly used bottom sand. If you raise guppies or mini parrots, it is better to use this bottom sand. It will not muddy the water, and it can also adjust the hardness of the water body. In addition, some aquatic plants can be planted on the ceramsite to provide a place for small fish to escape, and also to release oxygen.
2. Rain forest sand: Rain forest sand is more suitable for raising South American series of fish, such as brontosaurus, lantern fish, rat fish and so on. You can put sunken wood in it and plant some large-leaved water banyan. Because the sand is very fine, the fish's feces will not fall into the pores, and it is also very convenient to clean up.
3. Makeup sand: The color of the makeup sand is white, which is more suitable for matching with Sanhu cichlids. It is very beautiful to match, but there are also some inconvenient places, that is, because the color is too light, fish feces are easily exposed, and it is also very troublesome to clean up.
