Blue-green algae (type Cyanobacteria) cyanobacteria Anabaena, Aphanizomenon and MicrocystisThey are plaque of a characteristic color with an unpleasant odor. Not as common in the aquarium, but among the most dangerous. Formed due to stagnant water and the presence of a large number of nutrients. Isolate is a dangerous toxin that is detrimental to the living organisms of the aquarium.
Green filamentous algae (edogonium, rhizoclonium, spirogyra, cladofora) – the so-called. “Filaments”, (division Chlorophyta)They are represented by bright green threads, short hair-like or cobweb-like algae. They appear in water where ammonium is present and the nitrogen cycle has not been established. If the owner of the aquarium does not attach importance to the use of fertilizers.
Red Algae (Rhodophyta Division) – Crimson, VietnameseWhen they appear in the aquarium and on aquatic plants, not only the appearance suffers, but also red algae have a detrimental effect on the flora of the environment.

additional instruction about using Tetra Algumin Plus

It is known that some algae make an aquarium unattractive, inhibit the growth of aquatic plants, and negatively affect the biological state of the entire aquatic environment. And if you do not start a fight with them, the situation will only get worse.

If you start using Algumin Plus for preventive purposes, you can reduce the likelihood of the growth of parasitic plants in the aquarium. At the same time, the rest of the flora and fauna of the aquarium will remain safe.

The manufacturer is constantly improving its products. So, since 2015, the composition of the drug has changed: now Algumin Plus does not contain humic acid (peat extract), and the percentage of monolinuron in it is increased. This made it possible for the drug to effectively fight against all types of algae. Aquarists often refer to this product as the liquid alternative to Algizit.

It should be borne in mind that due to the content of humic acids, the drug gives the effect of “black water”.

prevention for overgrowth of algae

In order to prevent the appearance of harmful growths, you need to know about preventive measures. The main ones are:

  1. Finding the right place for your aquarium. If direct sunlight hits the water, algae growth is possible.
  2. Constant water change.
  3. Creating the right growing conditions for the plants in the aquarium.

Now you can dwell on the important points in more detail.


To stop negative growths, you need to know the composition of the water. The growth of such pests is primarily affected by the penetration of sunlight and excess nutrients. To prevent algae from continuing to develop actively, it is necessary to reduce the intake of trace elements such as phosphates and nitrates.

The temperature indicator is also important: if the water is warm, the algae will begin to multiply. The presence of excess nutrients in the liquid also promotes the growth of parasitic plants. We need to reduce them. Well, the increased rate of decomposition of ammonia NO2, NO3, also contributes to the appearance of harmful vegetation in the aquarium.

The water should be changed regularly. But this is not a panacea for the complete destruction of parasitic algae.


There are some algae-eating animals that can help improve the situation. This is Daphnia. Previously, all living creatures are removed from the aquarium and algae eaters are launched, which in a short time cleanse its contents from parasitic plants.

Algae-eating fish include:

  • Siamese algae eater
  • Ancistrus

They may not completely eliminate the problem, but they will take over most of the work. Purchase for the aquarium and viviparous fish, which, like shrimps, will eat algae, thereby helping the plants to cleanse.

And the last thing. Use chemicals in extreme cases when other methods of control have proved ineffective. Tetra Algumin Plus is reliable and effective, but you shouldn’t rely on it completely.

It is necessary to systematically take care of the aquarium: change the water in a timely manner, test its composition, carry out mechanical cleaning, adjust the aeration and filtration of the container with liquid.
