See It In Action
This video shows the Flow Pro aerator running with dual outlets, solar
operation and the day-to-night support of the battery backup model.
I chose this solar aerator as it's all in one - air pump attached to back of solar panel. It's a solid bit of kit which is working well, both in direct sunlight and in partial cloud cover. Good stream of bubbles and I like the options of day operation or at night or switched off. No noise from pump. I would recommend and happy to share photo of set up in new container pond (12 gallons).
