Setting up a new pond please help
 

Hi, I just finished digging a nice size hole, that will hopefully become
a beautiful pond. It measures 5.5 feet wide, 10 ft. long and 2 ft.
deep. If if figured correctly, this should hold ruffly 825 gallons. My
question is, is a pondmaster 1500 a good filter? It is suppose to be
good for up to 1000 gallons. Or is there a better filter option. I
plan to have plants and Goldfish. Any and all help is appreciated.
Thanks
