Ideas for Preventing Algae Growth in Your Birdbath

  1. Drop a few pennies in the water and leave them there. The copper will inhibit algae growth.

  2. Add a teaspoon of apple cider vinegar to the water to keep algae at bay. It won't harm the birds, and it keeps the birdbath much cleaner.

  3. Install a small fountain in the birdbath. Algae grows in stagnant water with low oxygen. By adding a fountain, it keeps the water moving and algae won't be able to survive in it.
