NFESOLAR Solar Pond Aerator, 2.5W Solar Aerator for Outdoor Ponds with 2200mAh Battery Backup, 3 Modes Solar Bubbler Solar Air Pump for Fish Pond Stock Tank Fish Pond Hydroponics Solar Water Aerator

The media could not be loaded.  This works well! With three variable modes, it kicks air bubbles out on all three. The box the panel cable goes into has an internal battery in it. So the box itself is not waterproof. So keep that portion away from water and out of the water if you can. The cells in the panel are a bit sensitive so when the glass in front of the panels gets dirty they are not as effective. But it is easy enough to clean off. Lots of cable length between the power box and the panel and they were generous with the hose, however. Better for indoor use, than outdoor since the power box is not water proof, but a certain level of water resistant.

The media could not be loaded.  I tried all settings and couldn't get it to make one bubble. I could feel the pump working but it's too weak and I was only using one air stone.

Got this to make a small deck pond for my wife. Everything plugs together easily. Because it's not weather proof I wound up putting the pump itself inside a waterproof container from Harbor Freight to shield it from the elements, and put the solar panel on the roof nearby. We'll see how it works once the weather gets better again!
