Can koi fish be released after pumping well water into the pool for three cloudy days?

First of all, remember to put koi fish in koi fish fish tank not too early. Even if you have used the best nitrifying bacteria, it will take three days to put koi fish in. It is harmful to put koi fish into koi fish fish tank prematurely. Because many novices can't master the water quality at first, and they can't clearly understand the influence of food residues and excreta on the water quality, it is enough to feed them once a day, so don't be afraid that koi fish won't have enough to eat. The continuous operation of the filter is also very important, and the nitrifying bacteria population on the filter material is the biggest guarantee for koi fish's health. It is forbidden to raise koi fish without changing water for a long time, and be careful not to change too much water when changing water. It is advisable to change water by one third, and the speed of adding water should not be too fast, at least for more than 20 minutes. Water quality stabilizer should be added before adding water.
