1. With the water level in the Fluval Edge™ tank reduced, apply power only to the EHEIM™ Compact 600© pump and wait for 40 seconds for the water from the MarinePac 3 to be pumped into the Fluval Edge™ tank.
2. Once the water stops coming out of the inlet/outlet assembly, disconnect the EHEIM™ Compact 600© from the power.
3. The Marine-Pac 3 is now mostly empty of water and easily removed.
