Why does an aquarium become covered with a green coating: 6 most likely reasons
The appearance of green plaque on the walls of the aquarium is caused by the growth of a number of algae, such as Euglena viridis, Oedogonium filamentosa and Xenococcus.
Let's look into the reasons that contribute to the excessive development of green algae. They may be as follows.
1. Excessive lighting
The aquarium should not be placed directly next to a window, exposing it to direct sunlight, and artificial lighting also requires strict control.
2. Lack of proper cleaning of glass, soil and plants.
Spores that linger in the soil, in scratches on the glass, on vegetation, contribute to the further spread of algae.
3. Incorrect choice of temperature mode.
4. Water replacement that is not carried out in a timely manner.
5. High levels of phosphates and nitrates
This point can be called the result of the previous one - untimely water change. During the process of water evaporation, the amount of salts in it increases, and if instead of changing the water you decide to simply add liquid, the situation will only worsen.
6. Too much food or inappropriate food
Leftover food that is not eaten for one reason or another settles to the bottom and begins to rot.
