The old way of breeding fish is a good experience.
If you adopt the old way, you will naturally not need to filter and add oxygen.
But there are prerequisites. First of all, your tank must be unglazed mud. Unpainted wooden tanks or tubs, like other tanks, whether ceramic, glass or plastic, are the same. Because mud and wood are breathable, other tanks will not have enough oxygen. p>
Second, dry the green moss in the tank, coat the tank wall with egg or taro, and let it dry for 1 week. Once the green moss is grown, the green moss will be raised during photosynthesis. . There is also a nitrifying bacteria seedbed used to break down harmful substances in the water.
The second step is to change the water every morning and 1 cup every morning. night.

The essence of ancient fish farming is to do nothing and follow nature. The original ecological tank basically cannot change water.
