The water tank must be strictly disinfected, and the method can use potassium permanganate (commonly used). The dosage is until the water appears deep purple, and then wash it with tap water several times.
After disinfection, add water, and add specially bought chlorine remover and nitrifying bacteria. Generally, the cultivation of digestive bacteria requires more than two months of water circulation and aeration and oxygen explosion during the cultivation. Fish can be released during this period, and parrot fish and goldfish are recommended, which is helpful to cultivate the nitrification system of fish tanks.
The ph value and hardness of water can be adjusted by changing water during hydroponics. If the ph is about 6.5, tds is lower than 100. Both grass mud pills and black peat can assist the process of changing water and adjust the pH of water.
Two months later, the angelfish basically landed in constant water and checked their ph and tds. Generally, the ph value is about 6.5, and tds80 is enough. Then, the new fish enters the fish tank. Let the fish adapt to the water temperature of the new water body before the young fry coming back from the water tank enter the water tank. Plastic hairtail is soaked in a thermostat, the temperature difference exceeds one degree, and the water temperature is kept above 28 degrees. After a period of time, the fry will be replaced and poured into a tank filled with constant water. Because the water body has an adaptation process, it is normal for the little fairy not to eat. Generally, a small amount can be fed after 24 hours, and it will get better slowly. In addition, the water tank can be put higher.
