Moments before spontaneously combusting lurker was heard to say:

its between Pondmaster 700GPH and the Pondmaster 950GPH, and you are
right either is plenty of pump for 120 gallons.

I have a 500gph on my smallest 150g pond. It works great - it filters as
well as runs the small waterfall. It filters because I set it in a plant
basket and wrapped plastic window screen around it. Nice, cheap, easy to
hose clean and the impeller is protected from trash.

im not sure if this
will make much a difference from the 500gph but i dont see the harm in
going bigger just incase.

That depends on the fish you plan to keep. Some, like fancy goldfish, don't
like a strong current.
