Koi is a cold-water fish, but its adaptability is very strong. Its adaptability to water temperature is very strong, between 5-30 degrees, it can survive normally. However, it also has the optimal temperature range for its growth, specifically between 20 and 27 degrees. If the water temperature is too cold or too hot, it will affect its development more or less.
In summer, the water temperature may be relatively high. In winter, the water temperature in some areas may be relatively low. At this time, manual adjustment is required. In summer, the temperature can be reduced by shortening the interval time of water exchange; In winter, some heating rods and other equipment can be used to raise the water temperature. Although the temperature is not suitable may not endanger its life, but after all, it will lead to its growth and development slowed down, is not conducive to viewing, it is recommended that the water temperature should be adjusted to the most suitable range as far as possible.
Generally speaking, the PH value is between 5.5 and 8.5, and the brocade carp can basically survive. However, the most suitable PH value for the growth and development of Koi is about 7.5, that is, slightly alkaline is better, its growth and development speed is the fastest in weak alkaline water environment, and it is not easy to get sick. If conditions permit, try not to choose acidic water, such water may lead to koi illness, growth and development will slow down. If you use tap water at home, pay attention to drying it first and then using it.
