Water tanks for marine organisms

The Flanders Marine Institute puts three water tanks at the disposal that are mainly used for research of fish. The water tanks could, for instance, be used as a quarantine to execute fish experiments.

How does a water tank work?

The cold store of the Marine Station Ostend (MSO) containing the two water tanks can be cooled/warmed at a temperature between 5° and 30°C. Each tank is completely separated from the other and has its own filtration system; a biological filter tank and mechanical filters. Each tank contains 4000 l water and can be cooled at a temperature between 5° and 20 °C.

Both the oxygen and the temperature can be adjusted in the water tank. The day- and night light are simulated as good as possible. In the future, a light dimmer will be installed.  

An ozon generator causes the death of the most important viruses and bacteria. A protein skimmer and drum filter are installed to remove respectively the unnecessary floam and flakes. Besides the temperature sensor, the water tanks also contain a redox sensor.
