1. New cylinder disinfection: Clean the new cylinder, disinfect with salt, and rinse 1-2 times. Fill the main cylinder with water, add water quality stabilizer to the main cylinder, and use an air pump to pump air into the main cylinder. Place the filter material properly in the bottom cylinder, but it is recommended that the filter material should not be too full when opening the cylinder in the early stage. Normally, the filter material should be filled by 1/2.
2.At this point, there is no need to turn on the main water pump and run your fish tank. A separate small water pump is used in the bottom cylinder, and a 1000L-2000L water pump can be selected for a 120CM-150CM filter cylinder. For sizes above 150cm, you can choose 3000L, but it is still recommended that the water pump should not be too large. Place a separate small water pump in the first stage water pump area behind the bottom cylinder, connect it with a hose, and then place the water pump outlet in the sensitive physical area, forming the framework of the bottom cylinder independent cultivation nitrification system. [Sensitive Words] Only 1/3 of the water in the bottom tank needs to be put into the water to ensure stable water quality. Turn on the water pump and heating rod.
3.After 3-5 days of operation of the filter cylinder, turn on the main cylinder water pump and stop the separate small water pump. Place the fish in the tank and observe the water quality and surface of the fish. If the fish in the tank is okay, you can release the dragon fish in 2-3 days
When there are one or more fish tanks, if purchasing a new tank, filter materials can be purchased in advance. Place the filter material at the water pump of the filter cylinder at the bottom of the old cylinder or inside the main cylinder. After returning home, disinfect the new tank with salt and rinse again with water 1-2 times. Put in about one-third of the cylinder block with new water. Add water quality stabilizer and inject air into the main cylinder without turning on the water pump. After 24 hours of operation, use a separate water pump to pump the water from the old cylinder into the new cylinder and fill it up (this amount can be controlled by oneself. For a mature cylinder, the water exchange rate can be controlled within 1/3 to 1/2. If the new cylinder is not sufficient, new water can be added). Take 1-2 pieces of white cotton from the old tank and place them in the new tank's "sensitive word" level filter. At this time, add new cotton to fill the "sensitive word" level physical area. Turn on the heating rod, turn on the water pump and run the new cylinder for~~~48 hours. Take out the filter material in the old cylinder (prepared for the new cylinder) and put it into the new cylinder. Add a proper amount of high-quality Nitrifying bacteria (50% of the standard amount). At the same time, add the Chuang Guan fish and continue to run for 3-5 days to observe changes in water quality and surface changes of the fish, if there are no abnormalities. On the day before releasing the dragon, change 1/4 of the water, add 50% of Nitrifying bacteria, 1 ‰ or 2 ‰ of sea salt. You can join the main fish the next day.
Keeping good water can effectively prevent many diseases, such as dragon fish water mold disease and dragon fish white spot disease caused by water quality.
