Our nets are above the water by
about 18".

Carol,
I've done as you suggested and bought a net. We are lost as how to put it over
the pond/waterfall and not hurt the plants. How do you have yours suspended?
Please give me as much detail as possible as I am a little simple when it comes
to figuring out this stuff. P.S. Scared our heron off twice already this
morning (man he is HUGE, looks you eye-to-eye). Thanks, Cathy
