The replacement 2-pack Air Stones for Pond Logic Airmax Aerators are 2 inches in diameter. They are designed for use with Airmax PondAir 2 and 4 aerators. However, the round air stone diffusers are universal and can be used with many other models of pond aerator systems!
These round, blue air stones produce fine bubbles, adding oxygen into the water column, improving the pond ecosystem.
