Additional info: I make the choice of lowtech to created the most natural eco-system as possible, not for my pleasure but for the confort of animals in.
I try any time to have the more natural process as possible, I never change water, never used chimical product.
I only ad water to compense the evaporation and cut the plants one time each 3 or 4 months, just for saved free place for fish.
INFORMATION ABOUT BIOTOPE
Description of the area surrounding the biotope: The lake take place in a mountainous region, in the middle of Myanmar. The country is in the tropical area of the world but Inle Lake is in altitude and that important because the meteorological conditions aren’t the same as the rest of country, we have tempered conditions around the lake.
The temperature move between 18 / 20°c in winter and 27 / 28°c in summer.
The water is clear the middle, but can came few dark on edge.
The chemical parameters oscillate almost randomly during the year because of the eternal conflict between the fresh and acidic water of the tributaries of the lake and the limestone nature of the rocky plateau. Generaly we have a PH stabilized between 7 and 8, some time he can be evolved, go down near 6,5 and go up to 9
Description of the underwater landscape of the biotope: On the edge of lake, we have root with plants, seaweed and on bottom you can see a dark mud.
In the middle the water is clear like mineral water. We have not surface plant in the middle of lake.
Description of the parameters of the habitat: The lake is fed by poor, sweet and acidic water that has passed through peat bogs while the lake basement is limestone. The lake is therefore dug by the homogeneous dissolution of the Shan plateau by acidic waters. The water from peat bogs is very poor in nutrients, so it is said to be oligotrophic.
