JMO, but I dont see why you couldnt use this. Its gph
is more than sufficient to handle the size of your pond. I have a bigger version of this one & have been using it to pump out the water on my pond project. But, what I will warn you about is this filter is meant to work below the water line. It will not pump above the water line without suffcient (and pain in the butt) priming though once it gets started, it works pretty well. What you may want to look into is a DIY filter- theres a bunch of U-Tube videos on the how-to mechanics of making one inexpensively using a trash can.
