The function and harm of algae how to remove algae effectively

Algae is always boring when it appears in a fish tank, because it is not conducive to the growth of aquatic organisms and does not have much landscape value. However, in fact, algae also has its unique role.

I. the role of algae

1. Because algae can produce oxygen and play an important role in the food web, algae are usually beneficial to aquatic organisms. However, if there is a surplus of algae, even the sudden rapid growth of a large number of plankton will also cause many fish to die.

two。 Larger algae, mainly kelp, are a popular food in the far East (Far East). They can be dried and compressed into a flat cake.

3. In Wales, there is a kind of red algae that can be used to make a flat bread called laver bread.

4. Algae are rich in vitamin C (vitamin C), vitamin B1 (thiamine) and potassium (potassium).

5. Algae are also widely used as feed and fertilizer for livestock.

Second, the harm of algae

Linear algae, carpet grass and silk grass are actually just several different names for a kind of algae. These various kinds of linear algae can be tangled up around the pool and float on the edge of the pool in a dark cloud shape, or form a dense, foamy layer of algae on the surface of the pool. Floating algae do not do much harm to the pond, but are unsightly. Although this or that kind of non-algae exists in most ponds, they generally do not cause problems in the case of natural balance. Algae may enter the pool in various ways, such as being brought in by the claws of birds, algae spores may also be blown in by the wind, and other aquatic plants may also bring algae into the pool.

The green water phenomenon is caused by thousands of single-celled plants-algae-in the water.

The emergence of a large number of algae is mainly due to the poor water quality caused by long-term non-replacement, incorrect and unreasonable lighting time, the deterioration of water quality caused by too many fish and aquatic plants, and the wrong introduction of species of aquatic plants with algae; poor fertilizer or the addition of excessive liquid fertilizer are the main reasons for the excessive growth of aquatic plants in fish tank.

Third, how to effectively remove algae

The main methods to remove algae are physical removal, chemical removal, biological removal and so on.

Physical cleaning: you can use brushes to brush, the market magnet brushes, fish tank brushes are very easy to use, but often do the whole tank of chicken and dog jump, and more than one tank is a big project.

Chemical removal: the effect of using algaecide is common, the advantage is that it is effective for any algae, and the disadvantage is that it has a certain impact on fish and ecological balance according to the quality.

Biological clearance: snails are often suggested to control the growth of algae. But although they can eat a lot of algae, they can't kill them as fast as they grow. In addition, snails have an unpleasant disadvantage, that is, they eat a lot of precious aquatic plants! Grass carp are also often used to control algae populations in some countries. But it's not a panacea either. After all, grass-eating carps don't eat different kinds of linear algae.

The above is an introduction to algae, which, like all algae, can reproduce very fast, so if a large number of algae are found in fish tanks or ponds, they must be dealt with as soon as possible. In addition, measures such as minimizing the amount of fertilizer in the water can also reduce the probability of algae overproduction.
