HEISSNER Pond Aerators & Solar Pond Aerators
For biotopes, garden ponds & fish ponds
Pond aerators guarantee a consistent oxygen supply to your garden pond and actively promote the water’s natural biological self-cleaning capabilities. Especially during the peak of summer, in ponds with high stocking densities, or where nutrient levels are elevated, supplementary aeration is vital to maintain stable water quality and prevent oxygen depletion.
The HEISSNER range includes both traditional electric pond aerators and modern solar-powered solutions for energy-independent operation. These systems are precision-engineered to suit various pond volumes and are designed for permanent outdoor use.

The roles of a pond aerator
A pond aerator facilitates vital gas exchange within the water. Using an air pump, ambient air is delivered through tubing to air stones. The resulting fine, rising bubbles saturate the water with oxygen while providing gentle circulatory movement.
- Secures consistent biological degradation processes.
- Promotes the vitality of beneficial aerobic filter bacteria.
- Counteracts the formation of anaerobic gases and sludge.
- Delivers measurably improved water quality.
- Acts as a life-saving measure during extreme heatwaves.
When does your pond require supplementary aeration?
- During intense summer periods, as warm water has a lower oxygen-binding capacity.
- In ponds with fish (particularly oxygen-sensitive Koi).
- In cases of visible turbidity or high organic loads from plant debris.
- As an emergency measure if fish are seen gasping at the water surface.
Optimal runtime for aeration
- During the warm season: Continuous operation is highly recommended.
- Water temperatures above 20 °C: Aeration should ideally be active 24 hours a day.
- Stocked ponds: Constant running guarantees the safety of your fish.
- In winter: Helps maintain an ice-free zone for gas exchange (depending on the unit and placement depth).
The rule of thumb: The warmer the water, the lower its capacity to store oxygen—precisely when the metabolic demand of pond life increases. Constant operation is particularly critical during sultry summer nights when plants also consume oxygen.
Synergy: The aerator and filter partnership
Absolutely! A well-aerated pond massively increases the efficiency of your pond filter. The resident micro-organisms require substantial oxygen levels to break down pollutants effectively. Supplementary aeration acts as a "turbo-boost" for biological purification.
