Buck, search for cement pond issues... Besides PH issues, from the high lime content, there are issues with... Black Algae, leaking, major stress cracks, you also need a steel frame. Arg, Fiberglass would be my first choice, followed by a natural clay brick and plastic tarped pond. Use the plastic under the clay and clay brick, not on top of it. Built like the reflection pool in Washington D.C., not like a classic slope banked pond.
Eventually the plastic will rot and crack, but will still help the clay retain water levels. Just don't build this within 80 feet of a fir tree, it will suck the pond dry and destroy the liner. (Sap and plastic don't mix, same with lime in cement!)
