The turbidity of the freshly raised fish tank water indicates that the nitrification system has not been built and needs to be reestablished. To establish nitrification system, it is necessary to add proper amount of nitrifying bacteria culture solution every week, and then turn off the lights and explode oxygen to promote its growth and reproduction. In this process, the water in the fish tank will become turbid first, and then slowly return to clarity, thus establishing a good nitrification system. In the daily feeding process, we should change the water regularly, but not more, and control the feeding amount at the same time.

1. Water quality is too hard: Water turbidity is usually due to too hard water quality, which means that there are more impurities, so it will become turbid after entering fish tank. However, it is very simple to solve the turbidity caused by this situation, just keep the filter on, and after a period of time, impurities will be adsorbed away, thus making the water clear.

2, Too much feeding: In addition to water quality problems, too much feeding can also make water turbid. Because the content of organic matter in water increases, microorganisms will multiply in large numbers, which will lead to biological turbidity. At ordinary times, this kind of situation can be avoided by reducing feeding, and attention should be paid to cultivating nitrifying bacteria, so as to improve the ecological cycle.

3. The light is too strong: If the fish tank is exposed to light for a long time, it will often cause algae to multiply and cause water turbidity. If you want to clean up algae, besides using algae remover regularly or raising several algae-eating fish, you can also control the light and feed to inhibit its growth, and finally make the water clear again.
