The aquarium facility consists of 40 tropical aquaria with a total operating volume of almost 5000 L. It is located at the ICBM in Wilhelmshaven. 30 x 100 L tanks are used for different experimental setups: Long and short term coral experiments, fish feeding assays and chemical ecological experiments with corals, algae or sponges. Temperature and CO2 can be controlled individually. All aquaria usually run in a recirculating system where ~ 5 % of the volume is exchanged with treated and analyzed North Sea water per week. However, all tanks can be run independently if needed. The Aquarium is run by Samuel Nietzer with assistance of Mareen Möller, Tessa Clemens and Petra Schwarz. We woud like to thank TRITON Lab for regular water analysis and Klimahaus Bremerhaven for the ongoing collaboration in coral research.
