This alga is a bit difficult to classify in terms of naming. This type of algae belongs to the Oedogonium family. Algae in this family occur with different lengths in their filaments and are a regular occurrence in our aquariums. We are dealing here with a green algae that grows hairs on the leaves of aquarium plants or on stones or wood. Just like beard or brush algae, the algae grows firmly on the substrate, but belongs to the green algae. It also looks a lot like thread algae, but remains smaller. This algae could also be the initial stage of hair algae. It seems as if the surface is provided with a fur (fur) or a velvet layer. Hence the appropriate name "Fluweelalg".

Like many other green algae species, this species also occurs regularly in newly started aquariums. Like many other algae, the cause can be sought in an imbalance in nutrients. Probably a shortage of CO2 and/or a shortage of nutrition. Too long a lighting duration as well as too intense lighting can be the reason for their presence.
The best way to deal with the algae is to promote plant growth. There is a regular shortage of Nitrogen(N) in an aquarium. So provide sufficient plant food, both macro and micro. Also ensure sufficient CO2. Do not give more than 8 hours of light per day and adjust the intensity downwards if necessary. Lighter types of this algae are eaten by snails, shrimp and some fish such as Mollies or Siamese algae eaters. Treatment with EasyCarbo can also cause the algae to die.
