the scale on the wall of the fish tank? If there is scale on the wall of the fish tank, you need to fish out the fish first, then drain the water in the tank, and wipe off the scale on the wall of the tank with a little toothpaste on the paper towel. In addition, baking soda and white vinegar can also be used to clean up, the effect is also very good, but must be cleaned several times after cleaning, in order to avoid these substances remaining in the fish tank, will have a negative impact on the water quality in the tank.
1, water quality is harder: can have furring, basically still be the reason of water. Household fish farming uses tap water. The hardness of tap water in different areas is often different. In some areas, the hardness of water is high and there are many impurities in the water. Although it has no effect on the human body, it will form scale in the fish tank, which will affect its ornamental value. Therefore, soft water resin and other means can be used to reduce its hardness.
2, filtration is not good: Although the water is not good, but if the filtration is relatively strong, scale is not easy to produce, so it also shows that the effect of filtration is not good. The filter must be high-power, the flow should ensure that all the water in the tank can be circulated 7-10 times in an hour, and there should be enough filter material in the filter tank.
3, change water rarely: If you pay attention to changing water at ordinary times, scale is not easy to produce, and if you do not change water frequently, scale will have a chance to adhere. It is usually changed once a week, and if the water quality deteriorates quickly, it is normal to change it once every three or five days. But if the filtering effect is good, it is no problem to change it once a half month.
