During the summer experiment 2016, the Stechlin Swings were first successfully used at the LakeLab. Like a second skin these tarpaulins hang in front of the actual enclosure walls. When after some time algae start growing in form of biofilms on the device, the Stechlin Swing is simply reversed to get a clean white side out again. The algae on the inside however will die within a short time because they get no light. During an experiment, the sides of the swing can therefore be rotated as many times as necessary to suppress algal growth.
Last month, Gonzalo Idoate Santaolalla and Ignacio Ajamil Rodanes fabricated the missing Stechlin Swings which were mounted today in the enclosures.
