It is best to lay some black gold sand, river sand, Dutch sand and coral sand in the guppy tank. These kinds of bottom sand are more suitable for the growth of nitrifying bacteria, especially coral sand, which can make the water quality weakly alkaline and meet the requirements of guppy for water quality. In addition, guppy has strong adaptability and low requirements for bottom sand, so these kinds of bottom sand are more suitable. Although these types of bottom sand are suitable for guppies, it is not recommended that breeders place bottom sand in fish tanks if the filtration system prepared by breeders for them is not strong. Because the filtration system is not strong, it is easy to hide feces and food residues in the bottom sand, resulting in an increase in bacteria in the fish tank.
2. How to keep the water quality of guppies1. Change water regularly: In order to keep the water quality of guppies growing clean, breeders need to change their water regularly. When changing water, we should pay attention to the temperature difference between new water and old water not exceeding 2 ℃, and pay attention to the amount of changing water not exceeding one third of the total amount of water.
2. Install filter: If conditions permit, it is best to install a circulating filtration system, which can not only keep the water quality clean, but also reduce the frequency of water change and reduce the discomfort of guppy.
3. Regular cleaning: To avoid deterioration of water quality, breeders need to clean up food residues and feces in fish tanks after each feeding. In this way, the water quality can be kept clean, and the PH value will not fluctuate too much.
