I have a birdbath that all of the birds seem to love. Unfortunately it has gotten a bad case of black algae. I've gotten a replacement birdbath (had it out for about 3 weeks), but the birds wouldn't use it. They'll sit on the side and then fly away without trying it. I finally put the original, algaed one back, and the birds are waiting in line to get in. Does anyone have ideas on how to clean it that will be safe for the birds. :-C
