Another option would be to use a diaphragm pump. These pumps can self prime, are highly efficient and can move lots of water. Best of all these pumps are low shear, so lots of pods etc. can safely pass through the pump. The one question that I have is if the pumps are "safe" for aquaria use as in the surfaces that contact the SW are inert.
An example of a pump can be found at
