How often can I use apple cider vinegar in my fountain and still keep algae under control but safety for birds drinking and bathing? Thank you

Our wildlife agent said: If you use 1 part vinegar and 9 parts water and a good stiff brush, you should be able to clean it as often as it needs it. You should just rinse thoroughly before refilling. Change the water every day or 2, before it gets too dirty, especially in the summer.
