Optimized Water Flow Dynamics
In 2019, Arnalax constructed four octagonal smolt tanks, each measuring 12m in diameter and 4m in height. To improve water flow dynamics and fish health, these tanks were designed with rounded corners featuring a 600mm (2ft) radius — a crucial design element that optimizes circulation and minimizes dead zones where waste can accumulate.
