Unless your fish are hanging at the top of the water gasping you dont need
an airstone.

I have read lots have natural ponds/VG filter no falls and they do not
talk
of the need for an air pump/stone. How necessary is a air pump/air stone
to
the health of the pond? Do you calculate size by gal with this type of
pump
also. If not what would be a typical size for a pond, better yet, what
do
you use? Joann

Sam, I think scientifically this is probably true, but if someone is
strangling you, would you like them to stop now, or wait until you turn
blue? Either way you will probably live, but which is really better? It's
cheap and easy to aerate.
