I have read in here that a small amount of bleach will not harm birds and it
does not take much to keep the algae down (1Tbsp?/Gal water).... That is
what I'm planning on using for a water fountain that I have. My concern
would be what it would do to the copper... Chlorine will react with the
copper unless it is really, really sealed well... I also believe that copper
chloride is toxic... Boiling water would kill the algae but also remove the
sealant...

We just got a copper fountain that uses about 10 little squirters.
It's developing a severe algae problem that clogs them up. Any
thoughts on what to put in the water to completely kill this stuff.
There are no fish or plants in it.

One thought I had is bleach, but how much? Is there a danger of birds
ingesting it or would they sense its presence and stay away?

Thanks,
