You can raise fish when the solar water is cold. After solar heating, it can also volatilize chlorine in water, thus playing the role of trapping water. However, it should be noted that if the solar energy equipment is used for too long, the water quality should be tested when changing water, otherwise it may lead to excessive heavy metals, thus affecting the health of fish, and even lead to their death.
1, drying: drying is the most common method of trapping water. Connect tap water to the basin, and then put it in a sunny place to insolate, using this method can trap water for only one day. If there is a drawback to this method, it is that it must be prepared in advance, and it can not be used in rainy weather.
2. Standing: Water trapping can be completed without light. It is enough to stand for a few days. Compared with the method of drying, the standing time is longer, and it should be used in time. Otherwise, if it exceeds a certain time limit, it is easy to cause a large number of harmful bacteria to multiply, thus reducing the quality of the water body.
3. Medication: The above treatment method takes one day at the fastest, but if medication is used, the chlorine in the water can be removed very quickly. Although this method saves time and effort, it will lead to drug residues if it is not used properly, which is also risky for fish.
4. Aeration: If there is an oxygen pump, it can also be used to aerate the water to achieve the effect of water trapping. It takes 1-2 hours, but it is more laborious. In addition, there are certain requirements for the power of the air pump.
