FAQ:

Q: How do you clean algae from a fountain?

A: In some cases, you can simply wipe the algae from the inside the fountain basin, allowing the water and loose algae debris to run through the fountain filter. Use a cleaning cloth or a sponge with a mild abrasive to wipe away the algae.

Q: How do you keep algae out of a fountain?

A: Empty the water from the fountain, either by tilting the fountain, siphoning the water or pumping out the water. Scrub the fountain basin with hot, soapy water made with a mild dish detergent. A solution of diluted bleach with one part bleach to nine parts water can help kill and prevent algae.

Q: Does vinegar kill algae?

A: Vinegar is a non-toxic solution for killing algae. A mixture of three parts water and one part vinegar can be sprayed on the algae, resulting in removal of the unsightly green growth while leaving nearby soil safe for other plants. Chlorine is often used to kill algae, but applying it to some materials can bleach them.

Q: Is algaecide safe for animals?

A: Algaecide used in indoor water walls and fountains may not be safe for use with fish and pets. There are algaecides on the market that are made specifically for controlling indoor water displays like fountains and water walls that may be harmful to living things, especially a pet drinking the water.
