We'll be away for two weeks in May and have a 450 gallon pond with at
least 2 dozen small to, mainly, large goldfish. It's just been cleaned
and new plants added, algae all gone, so there'll be little for the fish
to feed on. I see compressed disks of food available, but doubt that
they'd even last a week. Any suggestions on an automatic feeder we might
buy to use, nothing "fancy"?
