I used tap water to raise fish at home and died of illness. They say the water quality is getting worse and I can't raise fish. I want to ask, can tap water at home still be used for cooking?

Hello, landlord, tap water can't be used to raise fish, because there are many harmful substances such as chlorine in the water, which is harmful to fish. If the landlord wants to raise fish with tap water, he can expose the tap water to the sun for several hours, so it can be used in two days. Tap water can be used for cooking. After the tap water is cooked, the impurities in the water will disappear. This is a truth.
