Our mesocosm facility was set-up in Lake Erken (59°51′N, 18°36′E) in Central Sweden, which is a mesoeutrophic lake with ambient concentrations of TP at 31 µg/L and total nitrogen (TN) at 0.7 mg/L (unpublished average of 25 years of monitoring). The mesocosms consisted of 20 white opaque, open-top cylinders with a flat bottom, made of high-density polyethylene that were 2 m deep and had a diameter between 92 and 101 cm. The floating mesocosms were attached to a dock close to the lakeshore.
