Hi Jim,
AK! that is what always worries me
the most, a leak over the back of the stock
tank.
And it did happen once.
Pond was half way down and my sitter was
adding water slowly over two days to try and
get it back up but nothing happened as it
was still going over the back. No fish lost
thank goodness!

I've since given my pond sitter lots of instructions
about what to look for when that happens
and my phone numbers to call.

This summer we are so packed with obligations
that somebody will be home at all times so
no vacations here!

kathy :-)
