Best Floating Pond Aerators Ranked

8 floating aerators and aerating fountains.

Last updated: November 3, 2026

A floating aerator pulls water from below and throws it into the air, adding oxygen at the surface and giving the pond a spray pattern. It needs only an outlet and a float, and it can run in shallow water. Premium units from Kasco and Scott Aerator are built for year-round use and carry multi-year warranties. The 1 HP imports sell for a tenth of the price, with thinner support.
