how to control algae in bird baths

I saw a post on gardenweb not too long ago,… but can not find it any more using the search option. I was wondering what is the best sure fire way to keep a bird bath from becoming so grungy and scummy during the growing season? I just cleaned mine the other day, and frankly it was beyond nasty. The algae was so think in it. I try to empty it every 3 days and add fresh water,…(to keep the water clean & avoid mosquitos) and but the algae is relentless. It just keeps getting worse. Is there a natural way to curtail the growth? And what are some of the safer means to clean the bird bath, when I cant stand it anymore? I tried a scrub brush, and a scraper this time, but I was wondering if there are some natural products out there I can use to make the job easier and more complete? Baking soda maybe?

I was wondering if there are any natural products out there that I can use to make the job easier and more thorough. Baking soda, perhaps?
