Generally, the tap water needs to be aired for 24-72 hours to raise fish. The reason why there is such a big difference is that the speed of chlorine volatilization is different in different seasons. If it is summer, it only needs to be dried for 24 hours, while in spring and autumn, it takes 48 hours to ensure the dissipation of residual chlorine, and in winter, it takes at least 72 hours, otherwise it will affect the health of fish.
? 1. Bask in the sun: The simplest way to deal with tap water is to bask in the sun. Put the water in the sun and dry it for a period of time. The chlorine in the water will volatilize. The drying time is generally related to the temperature. If it is cloudy, the water may be trapped for a longer time.
2. Oxygen filling: In addition to removing chlorine by drying, oxygen can also be filled into the water, which can also accelerate the volatilization of chlorine and improve the dissolved oxygen in the water body, which is also helpful for the breathing of fish. Oxygenation dechlorination takes less time, but requires oxygen pumps and other equipment.
3. Chlorine remover: Usually, aquarium stores will use chlorine remover to treat tap water, because the amount of water needed is very large, and it is too late to rely on drying and aeration, but the efficiency of chlorine remover is much higher, but we need to pay attention to the dosage to avoid drug residues.
