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.
