mark i like your idea first off your siphoning idea will work wonders for you. if i was you i would go with a clay liner. with a 4 in pipe i would not worry about water flow. and oxygen issues how big are you going. the pond will not have to be very deep mine is 4 ft deep and the trout don't mind. instead of an aerator i would put the end of the siphon at the bottom of the pond keeping the bottom suplied with fresh water and oxygen it will be cheaper and you won't have to run electric. hope things go well for you good luck. how big is the pond going to be keep in mind the smaller the easier it will be to keep cool. what are your goals and how many fish do you want. these factors will determin if youl need to aerate or not.
