An affordable dual-outlet aerator with optional battery backup, delivering 1.5 LPM through each of two air stones for quiet, steady oxygenation in small ponds.
Choose between the solar-only and battery-backup versions based on whether you want daylight-only aeration or operation that can continue after the sun drops. The system runs either one or two air stones, so you can set up coverage to match your pond conditions.
✓ 2.5W or 3W solar panel✓ 3 LPM total air flow✓ Dual 1.5 LPM outlets✓ 500 mmHg air pressure✓ Optional battery backup
It is available as a 3W model with battery backup for extended operation, or a 2.5W solar-only model designed for daylight aeration.
Dual-stone aeration to support clearer, healthier pond water.

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).
