Method:
The treatment of bottom sand can be roughly divided into two steps, one is to remove impurities, and the other is to add fertilizer. In terms of removing impurities, just clean it with clean water, but to add the base fertilizer, you must first spread a layer of base fertilizer about 2cm thick on the bottom of the tank after cleaning, and then mix the base sand fertilizer at a ratio of 3:1 Spread a uniform base sand mixed with base fertilizer with a thickness of about 5 cm on the first layer of base fertilizer. Finally, spread a layer of base sand with a thickness of about 3 cm evenly on the bottom of the tank.
Note:
The bottom sand of aquariums is usually made of gravel. Gravel not only allows the growth of aquatic grass roots, but also promotes the reproduction of some nitrifying bacteria. Field, the water quality of an aquarium with bottom sand is more stable than that of an aquarium without bottom sand.
