After distilled water is purified, there are no impurities in the water, and there is also no oxygen, so fish cannot breathe in the water, and naturally it cannot be used to raise fish.Usually, fish farming still needs tap water, although there is more than chlorine residue in tap water, but chlorine can be volatilized by drying, such water is more suitable for fish farming.
1, drying: tap water fish must be dried, this can be done to remove chlorine, but also to raise its temperature.It should be noted that in different seasons, the drying time is different, it takes about one day in summer, two days in spring and autumn, and more than three days in winter.
2. Aeration: In addition to drying, aeration in water can also have the effect of removing chlorine.And the efficiency of aeration is higher, if the water is not changed much, aeration can be done for two hours, which can not only remove the chlorine in the water, but also improve the dissolved oxygen, which is very helpful for the breathing of fish.
3. Filtration: If the water is raised for the first time, it is best to filter it with a filter before putting the fish.The advantage of filtration is that it can filter out all the impurities in the water, so that the water will become clearer and more suitable for fish farming.Of course, the filtration equipment should be turned on all the time in order to maintain the water quality.
