the black mildew on the water pipe of the fish tank is actually brown algae, which is harmful to the water body and needs to be cleaned up in time. There are many ways to clean it up, such as scraping it off with an algae scraper, keeping some algae-eating tool fish and letting them eat it up, or using algaecide to remove algae. In addition, the growth of algae shows that the illumination time is too long, and the eutrophication of the water body needs to be improved.
? 1. Long illumination time: As mentioned above, the black mildew on the water pipe is usually brown algae, and the growth of brown algae is inseparable from illumination. Long illumination time will lead to a large number of reproduction. In order to avoid this phenomenon, the fish tank must be placed in the shade. Do not be affected by direct light for a long time.
2. Water eutrophication: Excessive nutrition in the water body can also promote the outbreak of algae. This situation is due to excessive feeding. The residual bait and feces in the water provide nutrition for the growth of algae. Therefore, the amount of food must be controlled when feeding at ordinary times. The fish tank should be cleaned regularly to discharge the dirt at the bottom of the water.
3. Weak nitrification system: If the nitrification system in the fish tank has been established, the ammonia nitrogen produced by the decomposition of organic matter will also be converted by nitrifying bacteria, which can also prevent the outbreak of algae. Therefore, we must pay attention to the cultivation of nitrifying bacteria and establish a good nitrification system.
