regularly. The rust in the fish tank is usually brown algae. The best way to suppress the growth of algae is to change the water. Usually, the water in the fish tank should be changed once a week. If the water quality deteriorates quickly, the water change cycle should be shortened. It can be changed once every three to five days. Each water change should not exceed one third of the total water volume, so as not to stimulate the fish too much.
of brown algae likes to grow in a dark environment, and light will inhibit its growth, so by enhancing illumination, it can also reduce its number and make the water clear. It should be noted that the fish tank should not be placed directly in the sun, so as to avoid long-term exposure to the sun leading to temperature changes, while allowing a large number of green algae to multiply.
The reproduction of algae is not only related to light, but also to the nutrients in the water body, and what increases the nutrients in the water body is the fish food. By controlling the amount of feeding, the growth and reproduction of algae can also be slowed down, so that the algae will gradually decrease, the water will become clear again, and the rust will disappear.
The drug algae removal takes effect very quickly and has a good effect. Commonly used drugs are glutaraldehyde, copper sulfate and so on, but the two can not be used together, otherwise it will lead to the loss of efficacy. In addition, in the daily feeding process, a small amount of algaecide can also be used to prevent the growth of algae.
