If there is less water in the fish tank, you can buy mineral water and pour it into the fish tank. If you use tap water, you must dry it for a few days before you can use it, because the tap water contains chlorine. If you use it without treatment, it will cause harm to the fish.It usually takes one day to dry in summer, two days in spring and autumn, and three days in winter.
1. Water trapping in advance: Water trapping must be used to add water to the fish tank. In addition to drying, aeration can also be used.The water was introduced into the container and aerated continuously for 18 hours with an oxygen pump.This method is faster than drying trapped water, and it can also provide oxygen content in water.
2. Appropriate pumping: If the water is to be changed, the water must be properly pumped before adding water.Taking some of the old water and adding new water can improve the quality of the water.When pumping water, one end of the pipe should be put to the bottom of the water, so that not only the water can be pumped out, but also the dirt at the bottom of the water can be discharged.
3. Pay attention to the water level: pay attention to the water level when adding water. Usually, the water in the fish tank cannot be filled up. Leave a pore of about 10 cm.Usually just add water to the same location as in the past.The water level must not be too high, otherwise it will increase the water pressure and increase the possibility of cylinder explosion.
