Prevent Algae from Growing in Your Birdbath

By flaflwrgrl

To keep algae growth from your bird bath drop some pre-1982 copper pennies in. I have what I would call a normal size bird bath & I use 7 pennies. The reason for the pennies being pre-1982 is that before that year, the pennies contained copper, a natural algicide. You could also use a small length of copper pipe or tubing, or any other copper coin. I have found this to work extremely well with the exception of those times when the temperatures stay above 90 for extended periods. Copper is not safe for fish so this would not be a good thing to use in a fish aquarium or a pond that has fish in it.

What works when the temps are above 90? I live in Florida and summer is here, whatever the calendar says!

I am in Fl. too & so I know what you speak of. The copper works pretty well but noting is perfect when the temps. get this high. The copper will keep it for a week to 2 weeks & then you'll have to clean it. Beats cleaning it every 2 or 3 days.
Also, instead of copper, you can use apple cider vinegar, just 1/2 cap per bath but you have to add it every time you fill the birdbath up or top it off.
I am a strong believer in the simple fact is that what matters in this life is how we treat others. I think that's what living is all about. Not what I've done in my life but how I've treated others.

Will the copper harm dogs or cats? Mine drink out of the fountain.

I can not say yes or no. All I can say is that if you use copper tubing rated for human use in human house construction that WE are safe drinking from then do you suppose it would be safe for your pet to drink from?
