7 Cents To Prevent Algae From Growing In Your Birdbath


Over time a birdbath can slowly have algae grow in it. However, copper pennies in bird bath may help you solve this problem.

Copper has biostatic properties that makes it incompatible with algae. Due to this, a basin, bird bath, container, bathroom sinks, or copper sinks will not trigger algae growth. But still, the bird bath must be regularly cleaned as excess copper in a bird’s drinking water may lead to poisoning and death.

If you place good luck coins made of copper on a concrete bird bath, there will be lower amount of algae build up. However, it does not ensure a 100% algae-free and bacteria-free bird bath.

By simply placing 7 to 10 copper coins pre-1982 into “normal size” birdbaths the copper… a natural algaeicide will help control the algae “extremely well with the exception of those times when the temperatures stay above 90 for extended periods.” [allthingsplants.com]
