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. |

Instead of using Liquid Nails, use Aquarium-safe silicone glue. You can get that at any BigBox petstore. It's perfectly safe.
I love this!!
They still haven't used the bird bath, and the water has evaporated every day, so I haven't had any slime growing. My Dad is going to love this too. He has to scrub his birdbaths every day because of the slime. His get used a LOT though. His country birds are a little classier than mine are! And, his birdbaths are in the shade, which contributes to the growth of that green stuff.
