I am so sick of my Magnum 350. I've replaced the magnetic impeller about three times now! This is because we have fine sand in our well water, and it gets trapped in the impeller chamber and destroyes the magnet. I was wondering if I could just buy a submersible pond pump and hook up the filters intake tube to the pumps outtake tube. Then I could just run the filter with the motor off and prevent more damage. Any help would be great. Thanks!
Would this pump work for a 50gallon?
