Did You Know?

Faucet aerators and aerating showerheads can be easily installed by homeowners to cut water (and especially hot water) use by as much as 50%. A lawn aerator removes little plugs of soil in order to let air deep into the soil, greatly improving the quality of soil that may have gotten too compacted. And a pond aerator, such as a fountain, is a necessity for an ornamental pond with no stream feeding it, since oxygen in the water is necessary to prevent the growth of algae and allow fish to live.

Examples of aerate in a Sentence
