CrystalClear PondAir 2, Complete Aeration Kit, Whisper Quiet Water Garden Oxygenation Bubbler System Adds Oxygen to Koi & Fish Ponds, Outdoor Aerator Compressor Pump, Tubing & 2 Air Submersible Stone

This is perfect for my small garden pond. The fish in the pond are more active and my allegehas been under control all summer. It was easy to set up. I would recommend this product.

I have a large goldfish pond and with two airlines I could have an air stone in the deepest area and one in a shallow area at the same time.

I waited to see how the pump would work through most of the winter before writing my review. The pump is installed in a small 2 foot deep water feature in my garden railroad. When I first installed the pump in September a slight cloudiness that I had been unable to clear up all summer disappeared within days. The pump is installed inside a model building to protect it from the weather. The control knob could be adjusted from a small bubble stream to what looked like a nice simmer. As the overnight temperatures dropped I noticed I needed to keep turning up the adjustment knob to maintain the same airflow. When the overnight temps dropped down in the low teens and single digits I had to turn the control up to full to keep the desired air flow. Even though the pond still iced over the fish did well and remained active. When the overnight temps stayed in the high 20s there would be a small open area in the ice. The sound level is low and it is masked by the falling water and stream when that is running. A great pump for a small pond.

Product came promptly and was easy to assemble. I installed in a bait live well holding approximately 300 gallons of water. Works well, but just think it is undersized for what I am using it for.

The media could not be loaded. Nice addition to our pond. I wanted to add extra bubbles to our pond on the opposite side of the waterfall. Install was very easy and I love that it comes with two balls for aeration with plenty of cord.

Great for winter for the fish,

Purchased this item a few months back for my outdoor water garden- it is still working. I am happy with the purchase and I think my fish are as well. 😊

Provides good aeration.
