place to add water to the fish tank? The water in the fish tank should be added to about four-fifths of the height. The reason for leaving holes on it is to prevent fish from jumping into the tank, and at the same time, it can also make the water surface contact with the air, so as to improve the dissolved oxygen in the water, so as to avoid the lack of oxygen in the fish. If the water level is too high, the pressure at the bottom of the tank will increase, which will not only affect the survival of some benthic fish, but also may cause the tank to burst.
1, drying: the new jar to raise water, first of all, the water into a clean basin, put in the sun to dry for a few days. There are two functions of drying, one is to volatilize the residual chlorine in the water, so as not to endanger the health of fish. The other is to allow impurities to precipitate so as not to form scale after entering the fish tank.
2. Oxygen explosion: In order to ensure sufficient dissolved oxygen in the water body, new water is usually used for oxygen explosion. The method of oxygen explosion is very simple. Prepare an oxygen pump and put the gas head into the water. Usually the oxygen pump has to be turned on for 24 hours so that it can be oxygenated all the time. If it is turned off, it will increase the risk of hypoxia.
3. Bacteria culture: Fish culture is also a key step, so as to establish a good nitrification system, so as to better maintain water quality and reduce the possibility of fish being poisoned by ammonia nitrogen. During the cultivation period, it is necessary to turn off the lamp and explode oxygen, so as to promote its growth and reproduction, during which the water will be turbid first and then clear.
