Hey, more questions I am trying to decide where to put my pond for the geese and runners, I have a slope near the house where my garden and fruit trees are, Is it safe to water my food garden with "duck water'"? (I already dump my old horse manure in it in the winter) or should i just water my trees and grass with it..... I was thinking about a pump/filter like a pool sand filter, that you could backwash... it is a preformed pool , but it willhold 165 galloons, course I could fill it partially with rocks to hold less water and add a drain pipe..... I also have a 'drycreek 'I filled with rock for water to drain around our house as we graded the house location with a higher back yard that goes up to my arena that has a fair amount of water come off it.... I was thinking about connecting the two, andybody here have a garden , waterfall, duck pond?
