If the fish tank is kept for 12 hours during the day, the appropriate temperature and sufficient light can make the chlorine in the water dissipate completely. Such water is basically suitable for fish farming. If the water is kept for 12 hours at night, the chlorine in the water can not volatilize completely, or it will cause some harm to the health of the fish, so it can not raise fish.
1, drying method: The most commonly used method of water is the drying method, this method is relatively simple to operate, as long as the water to be prepared in advance, put it in the sun, one to two days later can be used. However, the drying time should not be too long, otherwise the invasion of harmful bacteria will be harmful to the fish.
2. Explosive oxygen method: In addition to chlorine through drying, explosive oxygen also has the same effect, and it can also improve the dissolved oxygen in the water body, which is very helpful for the fish to breathe. And compared with the drying method, the explosion oxygen time is shorter, if the water is changed, generally only 1-2 hours of explosion oxygen is enough.
3. Medication: If you do not have oxygenation equipment, and you want to be able to quickly raise water, then the best way is to prescribe medicine. Many aquarium stores use this method to remove chlorine, but you must choose the right medicine, and at the same time control the dosage, so as not to cause harm to the fish by drug residues.
