Hi Larry,

You can read the algae primer (link in my sig) for
everything you ever wanted to know about algae.

If your labs are showing too much interest you
can always use an electric fido fence.

I have two labs who don't swim (much to my DH's
disgust ;-) the only duck they've ever carted around
is a stuffed toy duck...
Anyway, they don't bother the pond after their
puppy years when they dug in the mud and picked
spawning goldfish out of the water.
