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.

No, it will not but you need to make sure they are pre 1982 pennies. There is a lot of zinc in pennies minted later than that & that could possibly harm the birds.

Copper kills fish. There is no doubt about this. So I would not take the risk with birds.

If you will reads the comment threads on here you will find this has been thoroughly discussed and gone over time & again & this is safe for the birds. It is NOT safe for fish but IS safe for birds. The Cornell Lab of Ornithology even confirmed it.
