a fish tank can be used for raising koi. The size of the fish tank should be determined according to the breeding density and the size of the koi. Small Koi is small in size, if the number is not large, you can choose a finished tank with a length of about 1.5 meters and a depth of about 1 meter. If the number is large, you can consider using a larger space cylinder. If you are breeding large koi, you can choose a larger tank or use a customized tank.
According to the size of koi, you can choose different sizes of fish tanks. If you are breeding large koi, you need to consider the use of ground tanks or finished tanks. The light transmittance of the two cylinder bodies is very good, and the two cylinder bodies can be cultured in a place where astigmatism can irradiate, thereby avoiding moving the cylinder bodies back and forth due to illumination. If the Koi is small, you can choose a round tank. The round cylinder has the advantages of small volume, limited idleness and convenient cleaning.
In general, if the water is changed frequently, it is OK to clean the tank once a month or so. If it is inconvenient to change water, it is easy to breed microorganisms in the tank, and the tank needs to be cleaned every week. It should be noted that Koi need to turn on the filter all day. This can not only reduce the growth of bacteria, but also increase oxygen to the fish tank to prevent the death of koi hypoxia.
