CrystalClear PondAir Aeration Kits provide a simple, energy-efficient way to add oxygen and gentle circulation to smaller ponds and water gardens. Available in PondAir 2 and PondAir 4 configurations, these complete kits are designed for ponds up to 1,000 or 2,000 gallons and up to 2 feet deep. Each system uses a whisper-quiet diaphragm air pump with adjustable airflow control, flexible airline, directional check valves, and 2-inch air stone diffusers. The result is dependable oxygen distribution that supports fish health, beneficial bacteria, water clarity, and overall pond balance. Quiet, Efficient Aeration for Small Ponds and Water Gardens PondAir aeration kits are designed for continuous operation while using very little electricity. The PondAir 2 uses only 4 watts, while the PondAir 4 uses 8 watts, making both models economical choices for year-round pond aeration. An easy-to-use airflow control dial lets you adjust output without tools. Directional check valves help prevent backflow when the pump is turned off, while the flexible black vinyl airline makes it easier to position air stones where oxygen and circulation are needed most.
