INFORMATION ABOUT BIOTOPE

Description of the area surrounding the biotope: Hello, when designing the aquarium, I especially wanted to sample the deep water of the rio negro river, imitate the natural environment of my fish as much as possible. I used plenty of root and oak leaves, I reduced the pH of the water using licorice root and JBL active mec. water values ​​were adjusted to be exactly the same as the natural environment of living things. The current was slow towards the floating, 2700k daylight was used according to the balance of day and night of the lake. Styrofoam which does not oscillate into 3D water was used as background. The entire design of the aquarium and all the materials collected were taken from nature. Last but not least 🙂 Thank you for organizing such competitive competitions.

Description of the underwater landscape of the biotope: I arranged the underwater view as much as possible on the light rocky part of the rio negro lake.

Description of the parameters of the habitat: The temperature is 24 degrees in winter and 26 degrees in summer. Since the pH of the oscillation decreases in winter, it can be adjusted between 6,50 or 6,89 according to water temperature in summer.
