brown algae in the fish tank? If there is brown algae in the fish tank, it is better to clean it manually. Before cleaning up, you need to catch the fish and drain the water first, and then use the algae scraper to clean up the algae. In addition, you can also raise some algae-eating fish, such as black line flying fox, small elf fish, black Mary and so on, which can also eat algae in the water. Or directly use algaecide, as long as the dosage is well controlled, there is basically no problem, and it can also be used for prevention at ordinary times.
1. Control the illumination: To prevent algae explosion, first of all, we should control the illumination. The longer the illumination time, the easier it is to cause the growth of algae. Fish tanks can be placed in the shade at ordinary times, and special aquarium lights can be used to fill the light, which lasts 6-8 hours a day, so as to meet the needs of fish.
2. Reduce feeding: The main reason for algae explosion is eutrophication of the water body, and the source of nutrients in the water is fish food, which can also play a preventive role by reducing feeding. However, the reduction of feeding can not be fed, fish malnutrition is easy to become old fish, thus affecting their development.
3. Change the water regularly: By changing the water regularly, the addition of new water will change the water quality and inhibit the outbreak of algae. The cycle of changing water is not fixed, it depends on the change of water quality. If the fish tank is small and there are many fish, it should be changed every few days. If it is a big fish tank, it can be changed every half month.
