The fish tank water is not as clear and transparent as possible. As the saying goes, if the water is too clear, there will be no fish. If the water is too clear, the fish will not be able to survive because of the lack of beneficial ions and microorganisms. Therefore, the water suitable for fish farming is not necessarily particularly clear, many fish are suitable for raising in green water, but this kind of water will have a certain impact on viewing. It is also worth mentioning that some harmful substances are invisible, so although the water is clear, it does not mean that fish can grow healthily.
in fish farming 1. Filtration: The best way to maintain water quality is filtration. There are a lot of filtration equipment, the big one is not necessarily suitable, we must look at the flow, to ensure that the water in the tank can circulate about 7-10 times in an hour. In addition, the filter material should be complete, including filter cotton, activated carbon and bacterial house.
2. Change water: In addition to filtration, there is another way to improve water quality quickly, that is, change water. Usually, the water should be changed once a week, not too frequently, otherwise the fish will be stimulated. In addition, the amount of water can not be too large, usually about a quarter of each time.
3. Oxygenation: To maintain the water quality, we should not only look at whether it is clear or not. If conditions permit, we should also measure the ammonia nitrogen content in the water. If the content is relatively high, the scale of nitrifying bacteria is insufficient. In order to promote their reproduction, we need to turn off the lights and explode oxygen for a period of time, so as to establish a nitrification system and improve the water body.
