Can you keep Koi without turning on the pump at night and without turning on the light at night

Whether Koi need to turn on the pump at night depends on the breeding density and the breeding environment. If the breeding density is too high, the filtration and oxygen pump need to be turned on all day. If the density is not high, the oxygen pump can be stopped at night, but the filtration needs to be turned on all day. If the indoor temperature does not exceed 30 ℃, it is generally unnecessary to turn on the oxygen pump and turn on the filtration. However, if the temperature is too high, the oxygen pump needs to be turned on all the time, so as to avoid Koi hypoxia due to high temperature. 1、 Can you keep Koi without turning on the pump at night? If the weather temperature is not high and the fish tank density is not high, you don't need to turn on the pump at night. Just turn on the filter. If it's hot, cloudy and rainy, you need to turn on the oxygen pump for the fish tank. The purpose is to increase the dissolved oxygen in water and avoid casualties of Koi due to hypoxia and asphyxia. When it is necessary to heat up the koi for treatment, it is necessary to turn on the oxygen pump at night, preferably during the day, so as to avoid the aggravation of the Koi. 2、 Do you mind not turning on the light at night? If the Koi are cultured in places where the light cannot be reached, the light should be turned on and the artificial light should be used to irradiate the koi instead of the sun. If you breed Koi in a place with sufficient light, you don't need to turn on the lights at night. 3、 In those cases, you can turn off the oxygen pump. In the case of normal filtration, low fish density, wide water surface and no hypoxia, you can turn off the oxygen pump at night. If the water body of the maintenance environment is vast, there is live water injection, the environment is suitable, the filtration is good, the pollution is cleaned in time, pay attention to ventilation and proper sun exposure, such as Koi in the park landscape pool, oxygenation is not required in most cases. However, if the weather is muggy and the temperature exceeds 30 degrees, it is necessary to turn on the oxygen pump to avoid Koi anoxia due to high temperature. （YangJinLiWanShangBuKaiBengHangMa，WanShangBuKaiDengHangMa）
