Here's another thought: were the people using algaecides? I don't use any,
because the label said that it should not be ingested by animals -- don't
recall if that meant as is, or when diluted in the pond, though.

Of course, life with algae is much easier now that I've learned that the
stuff on the side of the pond is OK and shouldn't be removed.

Someone I know just tore out their preformed pond because they thought
their
dog got sick from drinking the water (I'm not complaining since I now have
a
new pond...I just have to decide where to put it and start digging). Does
anyone know if this is possible? DK
