Sometimes using a fountain cleaner is the only means to get your water feature in optimum shape. Routine prevention can save you the trouble of having to clean out your fountain of algae.  

An alternative to a fountain cleaner is adding barley to your water. Barley is more of a preventative measure than a fountain cleaner, which makes it even more effective. It works by preventing new algae from forming in your fountain, whether you have a wall fountain, waterfall fountain, a tabletop version or a pond.  

There’s another bonus to using barley as a fountain cleaner alternative – you can purchase a small bale of it without spending very much money. They are also sold as "Barley Pads" which work in the same way.

Hint: By also keeping your outdoor garden fountain in the shade, you help prevent the growth of algae in your fountain.
