If there is dirt on the fish tank, the fastest way is to clean it manually. Generally, dirt is water alkali, which is caused by the high hardness of water body. If you want to clean it up, you'd better prepare some toothpaste, smear it on the cloth, and then gently wipe the dirt. In addition, it can also be wiped with white vinegar or citric acid, and the effect is also very good.

If you want to clean up dirt, you can raise some tool fish, such as scavenger fish, golden moss rat, elf fish, etc. They have a wide range of feeding habits and can eat a lot of things. The dirt on the cylinder wall can also be eaten, and it will not endanger the health of fish, so don't worry. Moreover, this cleaning method is very environmentally friendly and does not need other means.

If the dirt on the fish tank is algae, the most direct cleaning method is algae remover. Algaecide is usually divided into two kinds, one is copper sulfate and the other is glutaraldehyde. Their effects are similar, but it should be noted that they cannot be mixed, otherwise they will react and lead to failure. In addition, there is a strict dosage of algae remover, which may cause phytotoxicity if used too much.

Besides cleaning up dirt at ordinary times, we should do a good job of prevention. If it is scale, some means can be used to soften the water and reduce its hardness. If it is algae, control the light and reduce food feeding.
