A 2.5W solar pond aerator with built-in MPPT battery backup, delivering 3 LPM through two 30mm stones for quiet oxygenation that continues into the evening on stored power.
3 LPM total airflow — 1.5 LPM × 2 stones
Built-in LiFe 6.4V 1500mAh battery, MPPT charging
Two outlets work independently — place stones at different depths
Brushless DC diaphragm motor — low voltage, safe & efficient
2.5W polycrystalline panel + stake & wall/tilt mount included
A 2.5W solar pond aerator with a built-in MPPT-managed LiFe battery, delivering 3 LPM through two 30mm stones. The panel runs the pump and trickle-charges the 1500mAh battery during the day, and the battery takes over automatically into the evening — so the pond keeps oxygenating after the sun drops.
✓ 2.5W solar panel✓ 3 LPM total air flow✓ Dual 1.5 LPM outlets✓ 500 mmHg air pressure✓ 1500 mAh battery backup
Dual-stone aeration to support clearer, healthier pond water.
Advanced Dual-Stone Aeration System
Designed for steady, reliable aeration, the Flow Pro uses a brushless motor and dual outlets to distribute oxygen more evenly. Use one or two stones depending on pond conditions and seasonal demand.

Practical Benefits
Supports oxygen during cloudy spells
Helps stabilise daily oxygen routine
Weather-resistant housing design
Mounting Options & Panel Positioning
Shown: panel mounted on ground stake and wall bracket.
Includes both a ground stake and an adjustable wall / tilt mount, so you can angle the panel for stronger seasonal performance — useful as the sun's path shifts between spring and late summer.
Pond Size & Stocking Guide
Aeration needs vary with depth, fish load and temperature. Use this as a practical guide, then adjust stone placement and runtime to suit your pond.

Good daily support for koi ponds
Helpful for planted ponds
Use dual stones for wider coverage
Supports oxygen during peak demand
Large Ponds
2000+ gal (9000 L+)
Useful as supplementary aeration
Ideal for local oxygen “hot spots”
Consider multiple units if needed

This video shows the Flow Pro aerator running with dual outlets, solar operation and day-to-night support from the built-in battery.
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).
