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
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?
