 Just pull off the 90 degree elbow that connects to the return fitting (it is just a friction fit) and lift the pump with attached tubing out (after unplugging of course).  If the suction feet are really stuck to the bottom you may have to reach in a wiggle the pump to get it to let go.  I have a 14 biocube and this is how I remove mine for cleaning.  Hop this helps. |
