Choice tank

Use this dual choice tank to test the behavior of aquatic animals moving freely between two slowly moving water columns with differing water quality (chemicals, DO, pH, CO₂, turbidity etc.).  

The hydrodynamic design of the choice tank creates a sharp and stable horizontal gradient inside the 32 x 40 cm test area where the animal is given a free choice of movement between two water qualities. The water depth in the tank can be set to 5, 10 or 15 cm depending on the type and size of animals or the application.

The choice tank comes with flow meters for accurate matching of flow rates from two header tanks (if feeding the tank by gravity) or two recirculatory pumps (excl.).

We offer customer-specified tanks upon request.
