First, build a 4' by 8' frame of pressure-treated 2x12s on underlay,

and will have a lot of bottom area on the concrete so I'm concerned
about the temperatures.

I vote for this one, put a sheet of Styrofoam under, between the concrete &
liner (or pond shell), this will take care of the temp., not to mention add
cushioning. ) ~ jan
