fish tank, you can prepare some white vinegar to wipe it, or you can use citric acid. This is because the composition of scale is alkaline, so it can be neutralized after contact with acidic substances, so that it can be cleaned up. It should be noted that acid residues can cause fluctuations in water quality, which is harmful to the health of fish. After dealing with the scale, it is better to wash it several times to remove the residue on it.

Two, how to prevent the fish tank long scale

1, change the water source: want to prevent the fish tank long scale inside, the best way is to change the water source. Fish are usually raised at home with tap water, which is relatively clean, but the alkaline content is relatively high, especially in the north, so we need to change a natural water source, we can use river water or clean water to raise fish, so as to avoid scaling.

2. Strengthen filtration: In addition to paying attention to the water source, good filtration also plays a certain role in avoiding long scale. Good filtration can filter out impurities in water, especially water alkali and other substances, which will be adsorbed by the filter material. But after a period of time, it is necessary to replace it with a new one, otherwise the effect will be greatly reduced after adsorption saturation.

3. Treatment in advance: As the generation of scale is directly related to water, treating the water before fish farming can also prevent the generation of scale. The treatment method is very simple, that is, to heat it with water, or to soften it with soft water resin.
