Italy, Tuscany, Province of Siena
I present this biotope aquarium as a faithful recreation of a unique and fragile ecosystem: a summer pool of the Onsola Torrent, located in the Val d’Orcia, Tuscany, Italy.
The composition was designed according to precise ecological and aesthetic principles. The layout is based on a streambed of light-coloured limestone pebbles (white and grey) of different sizes, partially covered by ochre sand and fine silt, replicating the natural substrate observed in the habitat. Dark willow roots extend through the left side of the aquarium, creating structural complexity and natural shelter.
The main focus of the biotope is the interaction between vegetation and water movement. Native plants documented during field observations, including Potamogeton nodosus, Ceratophyllum demersum, and water mint, recreate the dense submerged vegetation characteristic of summer pools. Strong surface agitation generated by the DIY filter with two lateral outlets simulates the natural oxygenation of the torrent, supporting stable gas exchange and water quality.
