guppish likes to live in slightly alkaline water. Therefore, the pH value of water should be tested frequently. If the water is acidic, quicklime needs to be added to the water. The addition concentration is 1 to 2 mg per liter of water, and the quicklime is directly melted into water, and then sprinkled into the fish tank. In the process of breeding, we should also pay attention to the water temperature. Keep the water temperature at about 25 degrees, which is beneficial to the growth of guppy. If the temperature is lower than 18 degrees, it needs to be heated by a heating rod. If the temperature is higher than 27 degrees, it is necessary to turn on the oxygen pump for oxygen.

Guppies are suitable for living in water with PH value between 7.2 and 7.4, and can also adapt to neutral water. At the same time, some aquatic plants should be planted in the fish tank, which is beneficial to the rest of guppy. The water in the north is alkaline. Every time the water is suitable, the PH value of water should be measured. If it is not within the standard range, it is necessary to find a way to adjust the PH value. For example, add quicklime to water, or prevent small stones at the bottom for a long time. Small stones can separate minerals in water, which can increase the PH value of water. You can also add baking soda or big soda to the water. These two substances are weakly alkaline substances, which are milder than lime water. Big soda can also reduce the chlorine content in water, which is suitable for small fish tanks.
