The treatment methods of tap water fish culture are: drying water, trapping water, filtering and using baking soda. It is best to use up the treated tap water within two days. After use, empty the residual water in the bucket, clean it, and then lift the water up.

1. Sunbathing: The easiest way is to expose the water to the sun for a day. This method is energy-saving and environment-friendly, and can also increase the water temperature.

2, trapped water: in the absence of light, you can naturally leave the water for 7-8 days. When trapped in water, you must open the lid of the container, otherwise you need to extend the time appropriately.

3. Filtration: Tap water can be filtered by activated carbon, which can adsorb dirty things in water, and it is safe and effective to treat tap water without toxic and side effects.

4. Use baking soda: You can add a small amount of baking soda to tap water to neutralize the free chlorine in the water.

Fish farming skills

1, to choose a suitable container for fish, the larger the surface area of water, the higher the dissolved oxygen in water, and fish need oxygen, so according to the type of fish you choose, try to choose a larger container instead of a container that is too narrow and too small, which will be detrimental to the oxygen supply of fish.

Fish grow underwater, but they also need to adapt to the environment to live longer. Oxygen, water temperature and water hardness are indispensable. The fish tank should be placed in a well-ventilated, constant-temperature room, not in direct sunlight.

3. Change water frequently, because fish will excrete products. Therefore, it is necessary to change the water frequently while raising fish to keep the water clean, and at the same time, it can ensure that the oxygen content of fish is sufficient.
