    1 or 2 Returns?

    Hi All,

    New to this so go easy,

    Im in the process of upgrading my pond, and in two minds about the amount of pond returns. I will be using a 15,000 LPH pump through bead and UV then back into the pond through 1 or 2 returns?
    I want to achieve the best flow possible with this pump, and aim to use 2 inch pipe where possible although the inlets may have to be 1.5 inch
    The pond is a rectangle and will hold about 3,500 gallons.

    your ideas would be most welcome.

    My opinion, one 2 inch pipe is too small for 15,000 LPH (about 4,000 GPH) return to the pond.
