Algae – the fear of every aquarist. In this regard, in most cases algae are not harmful but rather are "only" disturbing for the eye. We have listed the types of algae that occur and what you can do against the "green pest".
There are different types of algae, however only a few are relevant for an aquarium. The most frequent algae types in our application are presented. Blue algae, red algae, green algae and brown algae.
There are many reasons for increased algae growth, however the most frequent cause is an over-abundance of nutrients.
To avoid increased algae growth, the nutrient cycle in an aquarium must function. If nutrients are added, e.g. through fish food, then nutrients must also be removed, e.g. through trimming of plants and/or a water change. In particular, frequent water changes withdraw the excess nutrients and thus help eliminate algae. There are other possibilities for solving algae problems.
