Additional Information The lake Houralnya (means "distillery" in Ukrainian), represented in my biotope tank, is located in the park zone to the north of Vinnytsia city.
The lake is relatively small, water into Houralnya comes from several streams and underground springs and is good for living organisms. Chemical parameters of water, however, are unstable and depend on seasons and weather (rainfalls, droughts, volume of water brought by streams).
The lake is shallow, water near the shores is heated up well, this contributes to the explosive growth of vegetation in summer. The shoreline is filled heavily with fallen leaves and tree branches (this reminds a blackwater river).
Everything (including water at the biotope launch) was taken directly from the lake
The biotope aquarium represents the lake in the middle of July
