- take the MTR Kowloon Station in West Kowloon center to Hong Kong Station, walk about 8 minutes from the station to central station, take the Sheung Wan train of Hong Kong Island line, get off at Sheung Wan Station, and get off at exit d to Hong Kong Macau wharf. (about 13 minutes' drive, octopus $7.9, one-way ticket $8.5)
1. Walk about 860 meters from West Kowloon station to Jordan station
2. Take Tsuen Wan line, pass 2 stops, and reach Admiralty Station

the ideal depth of the pond for raising koi is 1.5 meters, and the larger the area, the better. It can raise large Koi. Small pond for small fish, water depth 50 cm, 1 meter square pond can raise 20 cm of Koi 4

water quality regulation:
after spring, when the pond water temperature rises to about 10 ℃ or above, appropriate amount of fresh water should be added to the overwintering carp pond, which can not only supplement the water volume of the pond, desalinate the poison, increase the dissolved oxygen, but also increase the water temperature, and promote the early activity, early feeding and early growth of the pond cultured carp. In early spring, the water temperature is low, the koi have less activities and food, and the pool water should not be too deep. However, the newly built fish pond or the carp pond that needs to breed fish in spring should be provided with enough water. With the increase of water temperature, the water level of Koi can be deepened graally by feeding more. Generally, fresh water is injected every 7-10 days, and the water level can be graally increased to more than 1 meter in April. If it is found that the water quality is aging and acidic, it is better to change the water once and deepen the water level in time. When adding fresh water, do not inject a large amount of water each time to prevent temperature drop. When the water temperature is about 8 ℃, the activity of koi is weak and the scales are tight. It is not easy for Koi to be injured ring fishing or transportation. In addition, the water temperature is low, and the chance of infection is less< br />
ammonium salt is the fertilizer of plants, and ammonium ions can be directly used by plants in water. Ammonium in natural water mainly comes from the decomposition of organic matter in water and soil. Under the action of bacteria, nitrogenous organic matter is first decomposed into ammonium ion, and the excreta of fish also contains more ammonium
too much ammonium in fish ponds is harmful to the growth of fish. The content of ammonium nitrogen should not exceed 2 mg / L. generally, the content of ammonium in natural waters is not so high. If too much soybean cake milk is fed to fish ponds, especially when the phytoplankton in the pond water is not prosperous, the content of ammonium in the water can be greatly increased. The use of chemical fertilizer should also pay attention to one time, not too much, to apply less frequently
nitrite can not accumulate more in water because it is unstable and easily oxidized to nitrate. The nitrite content in fish pond water with organic fertilizer was higher. The high content of nitrite indicates that the water body is polluted by a large amount of organic matter containing protein. Therefore, the content of nitrite in water is often used as an indicator of water polluted by organic matter (such as feces)
nitrate, like ammonium salt, is also an essential nutrient for plants. Nitrate itself is not toxic and has high content in fish ponds, which is not harmful. However, if the nitrate content is too high, it indirectly indicates that there is too much organic matter in the water, which will cause the risk of hypoxia. The nitrate and ammonium content in the pool with abundant phytoplankton will not be too high, because phytoplankton will consume them quickly, but the content in this pool will increase correspondingly in winter.
