Kathy......So I don't need the layer of sand? We do have a bit of rocky soil
here, not to mention a huge Silver Maple whose days are numbered but has a
root system like I've never seen before. Unlike my hometown in Indiana, the
soil here is rocky and a bit more on the clay side (but not as bad as when I
lived in Missouri).

We have so much room, hubby keeps bugging me to decide on a spot. (I think
the fish and frogs would like to leave the garage sometime this
spring...lol) I'm pretty much set on nearer the garage off the patio,
because if we go beyond the slope, I worry about any lawn fertilizer getting
into the water.

Hi Lisa,

The reason they talk about underlayment is
to keep pesky rocks from working their way
into the liner.
Anything will work. Old carpet (no nails ;-)
layers of newspaper, anything like that.
We used newspaper and old carpet for 3,000
gallons, going on six years, no problems and
we have rocks with a capital R in our yard.
