How often should you change the water in fish farming and how much should you change?

How often do you change the water in your home for fish? 1. If the fish tank is a naked tank (that is, there is nothing in the tank except fish), it is usually enough to change the water once every three days, and the water change amount should be maintained at one-third to one-quarter of the total water volume. 2. If there are aquatic plants in the fish tank, it is usually enough to change the water once a week, and the amount of water should be kept between one-half and one-third of the total water volume. 3. The tap water just taken out of the water pipe may contain some chemical components and is not suitable for direct fish farming. It needs to be exposed to the sun for several days before being poured into the fish tank. 4. How often you need to change the water when raising fish at home is also related to the type of fish. For example, in an aquatic fish tank with colorful gods, you can only change one-fifth of it at a time; goldfish are dependent on water quality. At the beginning, if you change the water once a day, it will be difficult for the goldfish to adapt. 5. It should be noted that when changing the water, the fresh water should not be too cold. It is best to dry it until it is basically the same as room temperature before pouring it into the fish tank. How to raise fish and change water 1. Do not suddenly change the water frequency too high or too low. Initially, change the water every few days. It is best to stick to it, because changing the water irregularly is tantamount to tossing the fish and will make the fish "weak". 2. The temperature of the water change should not be too low and should be basically the same as the temperature of the original water in the fish tank. 3. There is no need to add any medicine when changing the water, only a small amount of nitrifying bacteria is needed. How long does it take to feed fish at home? 1. Feed regularly, preferably from morning to noon, once or twice a day. The amount of fish food should be kept within 5 minutes, otherwise it will cause waste of fish food and pollute the water quality of the fish tank. 2. Newbies may throw in a lot of fish food at once when feeding fish for the first time, which is unscientific. Goldfish will die directly from this. Tropical fish cannot survive, but in a contaminated fish tank, the fish may develop enteritis and their activity level will be greatly reduced. Novice fish farmers pay special attention to the environment in which they raise fish. 1. There should be fewer big fish in the aquarium. In other words, the density of fish farming should be relatively small, 1cm of fish per liter of water. This breeding density is the experience summed up by many seniors, and you must know it. 2. Filter arrangement. Filtration device in this sense refers to biochemical filtration. Removing impurities from water is no longer easy. Establishing a good circulation system and eliminating harmful substances in water through microorganisms is an indispensable system for improving the hydrological environment. 3. The speed of water flow should be higher. It depends on the type of fish. You raise fish from wenshui or even stagnant water. Can't you wash it with running water? This refers to making the circulating water flow greater than it can bear. 4. Keep changing part of the water every three to seven days. Old water is key to fish farming, but new water is also essential to stimulate the metabolism of fish and aquatic plants. 5. Put some ice cubes on hot days and some warm water on cold days. Why do people who keep fish always die? This question is often asked. The person who asked it basically had a preconceived notion that the fish was killed by oneself. There are many others who think this way. In fact, there are many reasons why fish will die. It is not the main reason why you only order part of the fish that is not suitable for fish farming. If you don’t believe me, try building a fish pond of several hundred acres and see if you kill the fish. Usually, fish are kept in small fish tanks, which do not supply oxygen and the rooms are not very ventilated. People need oxygen in pond culture, so if they are kept in a fish tank, they do not have a good natural living environment. If the water is not changed frequently, ventilation is poor, oxygen or light is insufficient. The fish food you feed may not be what the fish likes to eat. These factors add up to an easy death. Of course, there is also a place in Feng Shui called the blind corner, which is the corner where the sun does not shine. It is basically not used at ordinary times. There is just a place available and you put the fish there. This blind spot has the worst aura in the house. Basically, flowers are raised to death, and fish are raised to death.
