As the header, are they usefully? I am building a small wildlife pool,
and would quite like to have a smaller pool above, pump water from the
lower to higher one and let it "stream" back. I am living in the North
Midlands of the UK, so sunshine is not constant. I realise that the
"stream" would not be constant, but would the system work?
