Toilette fill valve adds water automatically. Ours has one of those black
cylindrical floats and sits in the corner of the pond (base in a rock-filled
tupperware rather than toilette tank). We never add water ourselves, it
keeps things full and adds when the level is down by abot 1/2 inch.

We're putting a lot of effort into a natural look, so we're doing our
best
to avoid a visible liner. I want to try and get the water right up to
the
edge if possible.

Problem with that idea is that normal evaporation can lower the water
level enough in one day to make the pond liner visible. Complete
invisibility is very difficult to achieve. You could use a large rock
overhang (not generally a good idea) or hanging plants around the edge
to hide most of the liner.
