Hydor Koralia 3G 1950 GPH Circulation Pump

Hydor P39501

Movement pump with a dual magnet mount that Hydor says holds on glass up to 15 mm thick, with two fish guards and a flow diffuser. Hydor's page sells the Koralia G3 as 5000, 7000 and 9000 l/h and gives the 7000 for marine tanks of 280 to 450 L (about 74 to 119 gallons). Its Amazon page calls this size 1950 GPH, 7381 L/h and 6.3 W, and Hydor gives 6.3 W to the 9000, so we go by its flow and hold it at the 7000's 450 L.
