to raise fish in tap water. It takes one to three days to raise fish in tap water. In some places, it even takes about a week. The reason for this is that the tap water contains residual chlorine, although the content is relatively low, which is not harmful to human beings, but it still has an impact on fish. Therefore, after the water is connected, it needs to be placed in a sunny place for a few days, so that the residual chlorine in the water can volatilize cleanly and avoid causing toxicity.
for the water for fish farming? 1. Water temperature: The water temperature for fish farming is particularly important. Fish are poikilotherms, and their ability to adapt to environmental temperatures is far less than that of homeotherms. Neither tropical fish nor cold-water fish can accept dramatic changes in temperature, usually rising or falling by only 2 degrees Celsius a day. In addition, if tropical fish are raised, the temperature should be kept above 20 degrees Celsius.
2. Water quality: Whether the fish is good or not mainly depends on the water. Only when the water quality is good can the fish be healthy. There are two main ways to maintain water quality. The first is to change the water regularly and improve the water body by pouring out part of the old water and injecting part of the new water. The second is to maintain water quality through filtration, which requires a variety of filter materials.
3. Dissolved oxygen: Although fish live in water, they also need to breathe. They breathe with their gills and absorb oxygen through the flow of water. If the dissolved oxygen in the water is insufficient, it will often cause the fish to float and even die.
