If you want to regulate the water quality of guppy, the first thing the breeder should do is to change the water regularly to ensure the clean water quality in the fish tank. Only when the water quality is clean can guppy grow better and avoid the breeding of bacteria.

The second is to add some weakly alkaline filter materials or other articles, which can keep the water quality weakly alkaline all the time. The more common ones are coral bones, olive leaves, non-iodized salt and so on.

Finally, a circulating filtration system can be installed to slow down the deterioration of water quality. This can slow down the deterioration of water quality, reduce the frequency of water change, and avoid too much fluctuation of water quality caused by frequent water change.

It is best for guppies to change water once every 3-5 days, and the frequency of changing water is different in different feeding environments. If the breeder installs a circulating filtration system for them, he can choose to change the water every 5-7 days, and the amount of water changed each time cannot exceed one third of the total water volume. If the breeder does not install a filter, he can choose to change the water every 3 days or so. Pay attention to the temperature difference when changing water for guppy. Before changing water, it is necessary to adjust the temperature between new water and old water to be consistent.

The time of changing water for guppies is not fixed, and the breeder can decide the frequency of changing water according to the water quality of guppies and the size of water body. If the water in which guppies live is not dirty, the frequency of changing water can be reduced. If they live in poor water quality, the frequency of water change will be higher.
