What do you usually do when the water in your aquarium turns white? Can adding nitrifying bacteria help? Let me tell you, if you add nitrifying bacteria at this time, you are simply taking a detour and wasting money. Because most of the nitrifying bacteria products sold on the market are just water purifiers. They not only cannot effectively purify the water quality, but may also be harmful to the fish.

The Correct Way to Handle White and Turbid Water
We need to discuss two different situations.
White Water in an Empty Tank
When there is nothing in the aquarium, not even a single fish, and the water becomes turbid. This situation usually occurs because the substrate and filter media have not been cleaned properly, causing a large number of particles to be suspended in the water, making it turbid and white.
Solution:
- Let the water stand for a while, or
- Use a filter to filter the water for two days, and the water will naturally become clear.
White Water After Keeping Fish
If the water in your aquarium suddenly turns white after you have already kept fish. This is usually because your nitrification system has not been fully established, leading to turbid water quality.
Solution:
- Patiently wait for the nitrification system to gradually establish itself, which usually takes 21 days to a month.
- During the waiting period, reduce the amount and frequency of feeding to alleviate the workload of the nitrification system.
- About a month later, when the nitrification system is fully established, the water quality will naturally become clear.

Thanks for clarifying the nitrifying bacteria myth! What are some early, reliable signs that an aquarium’s nitrification system is truly establishing itself?
@CriticX:感谢您的提问!硝化系统建立的初期迹象,最直接就是水质逐渐变清澈。文章指出,此过程需21天至一月。耐心等待是关键。
