Copper Piece Keeps Bird Bath Clean

Somewhere, I read that putting a piece of copper  piping inside a bird bath would help keep the water clean.

It sounded a little weird  but that didn't deter me from giving it a shot.

Hubs has everything imaginable in his storage room and, when a piece of copper piping was requested, he produced it.

I put it into the bird bath and voila!  It really does help

keep the water clean.  

There is no longer any green scum of any kind  inside the birdbath.

Now the little feathered friends have sparkling clean water !  How cool is that?

The three layers of the fountain got some copper piping pieces, too! 

DO YOU SEE BIRDS AT A  BACKYARD BIRDBATH?
