Most people never think about the tubes inside a fish farm. Yet they play a crucial role in keeping the water clean and the fish alive and healthy, while minimizing the environmental impact.

Inside a fish farm in the Netherlands, thousands of yellowtail kingfish glide through large tanks in a slow, steady rhythm. The water around them is calm and clear but keeping it that way is not easy.

Fish farms must produce healthy fish, use water responsibly, limit their environmental impact and clean, filter and reuse the water, ensuring stable conditions day after day.

Stronger steel, steadier flow with Alleima’s tubes

That’s why the Dutch fish farm pays close attention to things such as the tubes hidden behind the walls of the tanks.

The Dutch fish farm found that regular copper and stainless steel tubes corroded under the demanding conditions. But with Alleima’s tubes, the flow stayed steady, and the water stayed clean.

“It is about understanding the whole system and finding a solution that lasts,” says Bernardo Size Vieira, Technical Marketing at Alleima.

Most people never think about the tubes inside a fish farm, but they are there below the surface, quietly keeping everything in balance.
