We started so nicely with our aquarium experiment by adding 0, 1, 2 or 3 droppings to mesocosms with Daphnia in heated and unheated aquaria. But after three days, the Daphnia died and the pots became smelly. We expect the droppings, collected at the Sagbruk area but maybe containing some pollution like coal.
That is why we restarted the experiment and Catharina is filling the pots with the same amount of droppings collected close to Solvatnet.
