    Pond is 20'x20', 5' deep, 75 sq ft stream.

    Also on a pond this size will I need an aerator in it?

    May need an aerator or heater in the winter in case of ice-over.

    Alway's get a little bigger, nothing is worse than having a low liner edge. Liner is also getting out of hand price wise so design to suit.
