About this item
Product details
CrystalClear PondAir 2 Aeration Kits are ideal for decorative ponds and water gardens of up to 1,000 gallons with a maximum depth of two feet. Powered by highly efficient diaphragm compressors, CrystalClear PondAir Aeration Kits infuse your pond with vital oxygen while remaining whisper-quiet and cost-effective. An airflow control valve on the top of the pond aerator lets you adjust the aeration output to your pond with the simple turn of a dial.
If you experience murky water, debris accumulation, or struggle to maintain a healthy fish population, your pond may lack oxygen and proper circulation. As water temperatures rise and debris accumulates, the available oxygen in your pond's water plummets. CrystalClear PondAir aeration kits are perfect for aerating water gardens and koi ponds to ensure sufficient circulation and oxygen is available throughout the pond.
This koi pond aerator creates an environment suitable for aerobic natural bacteria to flourish and continuously clean your pond water. Aquatic plants will thrive, water quality will improve, and you will reduce muck, algae, and foul odors.
Choose between two aeration kit options based on your pond size. Each kit includes a diaphragm compressor with a six-foot power cord, two bubbler airstones, and flexible vinyl air tubing. Powered by a 115-volt compressor with a standard plug for household outlets.
- Small aerator for ponds - Increases water circulation and oxygen saturation, improving the natural ecosystem in small backyard ponds, water gardens, and koi ponds. 
- Improves water quality & clarity - Bottom-diffused pond aerators pump oxygenated air into key areas to support beneficial bacteria that clear murky pond water and eliminate muck. 
- Energy efficient & virtually silent - Electric compressor equipment operates quietly and runs 24/7, using only 4 watts of power. Aerate your koi pond for just pennies a month!
- Aerate all year - Use during the winter months to help keep a hole in the pond ice to vent harmful gases. PondAir aerator kits are also ideal for large aquariums, stock tanks, and hydroponic applications.
- Optional faux rock cover - Conceal and protect your aerator from the elements using a durable TrueRock Mini fiberglass fake rock cover with built-in ventilation.

Fantastic Aerator
I've had a few aerators in my time and this is by far the best one I've ever had. The power is amazing and I was able to cover both ends of my pond with the ample amount of air hoses provided. The multiple settings was a bonus!! My fish love it and it helps reduce algae growth.

Oxygenates the water
Pond aerator with 2 stones and optional mini tru rock cover has worked out great. Plenty of bubbles and the fish are loving it. Before use the fish were not swimming. I knew it had to be a lack of oxygen. The fish are swimming normally now. The cover protects the pump from the elements.
