Pond Aerator 1, Complete Aeration Kit, Water Garden Oxygenation Bubbler System Adds Oxygen to Koi & Fish Ponds, Outdoor Diaphragm Compressor Pump, Air Line & 1 Submersible Diffuser Stick

works great, strong flow of bubbles to help keep the water moving and oxygenated. I recommend this product

Works well in all weather conditions and the fish really seem to like it.

The aerator works well. It is keeping our pond water oxygenated for our koi.

Had the aerator a week and it seems to be doing the job. Easy to install. If I can do it, anyone can.

Not good for an AZ Koi Pond, unless you can cover the aerator and it's in the shade. You need to cover it with some type of faux rock, like I have. I have it under a medium sized faux boulder, but the boulder is in the Sun all day. I have no shade around the perimeter of the pond, so the faux boulder and the pump are in the Sun half of the day. The pump will overheat and shut off to protect itself, but it will not stay running if it's 90° and Sunny out. The pump works great and the fish love swimming through the bubbles, but it's useless to me since I can't keep it running. Too bad. It's not a bad pump. I still gave it 4 stars because it's a great addition to a pond if you have it in the right environment. AZ is just too dang hot for it. Update: I found this wouldn't stay running for me since it is so hot in AZ and I can't relocate this in the shade. I ended modifying a Faux Boulder I got at Home depot with a cooling fan and a thermostatic switch. This work great. I have the sensor set to turn the fan on at 90°+-3°. See photos.

Quality product !! Solid output . Very Quiet . Keeps our very new little pond so clean! Song Birds and raptors are not afraid . Dogs are not afraid to play around it in the water .

I was losing water from my pond and it was getting worse by the day. I decided to turn off the waterfall to see if that was the source. With the heat we’ve been having, I had to supply oxygen for the koi. I had purchased the Aquascape 4 disc aerator in the past and it didn’t last long. The discs came off and fell to the bottom then the unit stopped putting out air. The motor was running but not no air. Based on that experience, I decided to buy the one from The Pond Guy. When I unpacked the box I could tell this one was going to put out air! The hose is huge in comparison to Aquascape’s. It puts out more air with one hose than the other one with four hoses. Plus the line sinks so no ugly hose laying across the top of your pond. One issue I’ve had twice is that it suddenly stopped working. I am not sure if it tripped the circuit or if the unit overheated. I reset the circuit and plugged it back in and still nothing. Tried another outdoor outlet and nothing. I was about ready to pack it up and return for a replacement but made one last attempt. Plugged it back in to the same outlet and it worked. I’m baffled. If it happens again, I will send it back for a replacement. I’m having the waterfall rebuilt the middle of September when the heat wave ends. It took the koi about a week to adjust going from waterfall to aerator but they are fine now. Providing that the loss of power was not the unit, I do recommend this over others. It’s worth the extra money. And if it is the unit I will return for a replacement. It’s that good! UPDATE: I returned this unit because it shut down again. I ordered another one and it is perfect. It seems more powerful than the one I retuned. I had the leak repaired, the waterfall rebuilt and the pond pressure washed. It’s beautiful and I don’t think I’ll even need the heater for ice this winter because this aerator is that strong. I’m very happy with it and highly recommend it.

Great product. Would buy again.
