The green spotted algae on the tank wall can be treated in several ways:
1. Use tools to remove: You can use tools such as a scraper to gently scrape off the green algae on the tank wall. It is important to note that care should be taken when using tools to avoid causing harm to the fish.
2. Biological control: Introduce some algae-eating organisms into the fish tank, such as scavengers, moss rats, elf fish, black line flying foxes, rat fish, etc., which can help remove green spot algae. However, it should be noted that polyculture should ensure that they are similar in size and habits to avoid the occurrence of large fish eating small fish.
3. Increase carbon dioxide concentration: The growth of green spotted algae requires sufficient carbon dioxide, so its growth can be inhibited by increasing carbon dioxide concentration. Carbon dioxide equipment can be added to the fish tank, or the number of aquatic plants can be increased, and carbon dioxide can be produced through the photosynthesis of aquatic plants.
4. Control the light time and intensity: The growth of A. viridis requires light, so its growth can be inhibited by controlling the light time and intensity. The fish tank can be placed away from direct sunlight or equipment such as a visor can be used to reduce the light duration and intensity.
5. Regular water change: Regular water change can dilute the nutrients in the fish tank and reduce the nutrients of the green spotted algae, thereby inhibiting its growth. It is recommended to change the water at least once a week, and to take care to control the amount and frequency of water changes.
It is important to note that when dealing with Auritica aeruginosa, avoid using overly violent or dangerous methods to avoid harming the fish. At the same time, regular maintenance of fish tanks and keeping the water clean are also important measures to prevent the growth of A. viridis.
Achlorophyllum is not directly harmful to fish. It can be food for fish to a certain extent**. However, if there is too much green algae, it will affect the ornamentation of the fish tank and may affect the growth of the fish. When too much green spotted algae respirates at night, it will consume oxygen in the water, which may lead to hypoxia or even death of fish in severe cases.
Therefore, although Chlorella is not directly harmful to fish, it also needs to be treated regularly to avoid too much impact on the tank environment and the growth of the fish. Methods for treating Aeruginophyllum include the use of tools for removal, biological control, increasing carbon dioxide concentrations, controlling the duration and intensity of light, and changing the water regularly. When dealing with Auritica aeruginosa, it is necessary to pay attention to safety and the impact on the fish to avoid unnecessary losses.
