Raising goldfish requires maintaining healthy water quality. Here are some of the key steps to water conservation:
1.Understand the water quality: Before raising water, it is necessary to understand the local water quality, goldfish prefer alkaline water, and the pH value is about 75-8.0。If the local water quality is too acidic or too alkaline, it is necessary to adjust the acidity and alkalinity.
2.Drying fresh water: It is best to dry fresh water for a day before entering the tank to prevent the chlorine content in the tap water from being too high.
3.Water exchange: The amount of water and the frequency of water exchange should be adapted to local conditions according to the actual situation, such as the size of the feeding, the temperature and other factors. In general, the higher the amount of feeding and the higher the temperature, the greater the frequency and number of water changes.
4.Density and equipment: The density of fish should not be too high, generally 10L of water per adult fish (10 cm length of tail removed), and 1L of water per cm of fish body length is required. Large-density aquaculture requires additional equipment, such as aerators, water pumps, material filtration and biological filter tanks.
5.Cleaning and prevention: The tank must be thoroughly cleaned once a year, and preventive medicated baths should be carried out during the high incidence of fish diseases. Potassium permanganate, methylene blue, etc. should be always available.
6.Prohibition of medication: If it is not necessary, it is forbidden to administer drugs in the master cylinder. Medicated baths and diseased fish** should be carried out in the auxiliary tank.
In addition, different water depths are selected depending on the species. Generally speaking, pearls, blisters, orchids, butterfly tails and other species that are not good at swimming require a water depth of no more than 50 cm, and 30 cm to 40 cm is appropriate. The water depth of grass gold, koi, gilt and other varieties is more than 60 cm.
