? The chloasma in the fish tank is usually brown algae. On the one hand, the appearance of brown algae is due to environmental problems, such as long illumination time, or more organic matter in water, on the other hand, it is not cleaned up in time and water is not changed regularly. Usually, when the number of brown algae is not very large, it will not cause much harm, but it will affect the overall ornamental.
1. Proper shading: The growth of algae requires moderate light, so the best way to prevent algae explosion is proper shading. The fish tank should not be placed in a sunny place. It is recommended to place it in a bright place indoors. If the light is insufficient, you can install a special aquarium lamp in the tank to fill the light. The light is 6-8 hours a day, so it is not easy to explode algae.
2. Reduce feeding: The eutrophication of the water body is also a necessary condition for the outbreak of algae. By reducing feeding, the content of organic matter in the water body can be controlled. If they are less, the nutrients produced by decomposition will be less, thus avoiding the massive growth of algae.
3. Change water regularly: If you pay attention to changing water at ordinary times, the growth of algae can also be limited. Because changing the water will inject new water, the water quality will change and the growth of algae will be limited. It should be noted that the water should not be changed frequently in order to prevent algae explosion, so that the fish can not stand it.
