water machine, that is, to filter the trapped water. If you feel that it is troublesome to prepare water in advance when changing water daily, and there is no good filter in the tank, you can use it. Not enough, the price of this equipment is on the high side, the functionality is not too good, the cost performance is poor, so it is not particularly recommended, after all, the functionality is similar to the filtration, even not as good as the traditional filtration effect.
1, trapped water: want to raise good water, the first thing is to remit money. Because the water usually used is tap water, after disinfection by the waterworks, although it is not polluted, there may be residual chlorine, which is harmful to the health of fish. So continue to expose the water to the sun for a few days to allow the chlorine to evaporate.
2. Oxygen explosion: There are many ways to trap water. Besides drying, oxygen explosion in water is also a good choice. However, it should be noted that oxygen explosion can not only remove chlorine, but also improve the dissolved oxygen in the water. Only when there is enough oxygen in the water, the fish's breathing can be guaranteed, which is conducive to its survival.
3. Bacteria cultivation: The most important thing for water cultivation is bacteria cultivation. Although the nitrification system can be established sooner or later, in order to better fish farming, the time is naturally the earlier the better. Pour the culture material of nitrifying bacteria into the water tank once a week, and at the same time, turn off the light and explode the oxygen, waiting for the water to be turbid first and then clear.
