Simply put, an aquaponic system’s essential components, such as the water and air pump, keep the system running, hence its dependability as a power source is crucial.
An aquaponic system can be shielded from a power outage by having a backup source ready to keep the system running continuously. To ensure water circulation for the plants and fish and to supply dissolved oxygen, both the water pump and the air pump should be kept on.
The majority of aquaponic systems demand constant circulation of nutrient-rich water. RAS is the name of this system type (Recirculating Aquaponic System).
The air and water pump makes it easier for plants to acquire the nutrients and oxygen they need to flourish. An aquaponic system’s success depends on having a reliable backup system to provide constant power.
Knowing how to set up and build a reliable backup system will ensure that an aquaponic system continues to operate even in the event of a power outage.
However, there are a few steps that must be taken to achieve this, and we will go over each one so that you can have that piece of mind when you need it most.
See our comprehensive guide on aquaponics to learn all you need to manage a system successfully.

How Long can Fish Survive without Power?
Fish typically survive a power outage for four to six hours. However, the number of fish in the fish tank has a significant impact on this.
Like all other living things, fish need oxygen to breathe and maintain healthy cell activity. Both the water pump and the air pump stop working when there is a power outage.
This prevents dissolved oxygen, which would typically be provided by the air pump and agitation from the system’s water circulation, from entering the water stream.
Fish will start to grow anxious as the dissolved oxygen levels begin to drop since they will sense something is amiss.
When you notice the fish gasping at the water’s surface, it’s a good sign that the oxygen level in the tank is low. You’ll be able to tell that your fish require additional oxygen at this point.
Since this is the only location where oxygen is entering the water, fish move to the surface. But typically, this is insufficient to meet their ongoing oxygen needs, and they finally perish.
How Long can Aquaponic Plants Survive without Power?
Depending on the type of aquaponic system, plants can survive for 24 hours.
The reservoir of water that the plants and their roots must draw nutrients from allows them to survive for a long time in aquaponics systems like Grow beds and Deep Water Culture (DWC), frequently outlasting the length of a power outage.
The plant pots in grow beds and DWC systems are made to hold water. There will always be water for the plants to get nutrients from even if the pump breaks down. In the event of a power outage, the plants will survive thanks to the residual water.
These kinds of devices can be employed while creating an aquaponic system to safeguard the plants in the event of a power outage.
Not all aquaponic systems are likely to be as fortunate.
An NFT Aquaponics system allows for a maximum of 8 hours of plant survival. This is due to the NFT system’s lack of a water storage from which plant roots might continuously draw water and nutrients to survive. The roots are left dry when the water drains into the sump tank.
Before the leaves begin to wilt, the plants will remain upright for two hours; after that, things will only get worse.
How to Keep the Fishes Alive during a Power Failure?
Having a backup air pump to fill the fish tank with air will keep the fish alive if the power goes out. In the event of a power outage, a variety of backup air pumps are available to provide an unbroken flow of air.
The Fulhengy Battery Aquarium Air Pump and the Penn Plax Silent Air Pump are the two pumps I’ve discovered to function the best.
You must take the size of the fish tank and the number of fish in the tank into account when selecting a backup air pump (fish density).
During a power outage, the fish density may have a significant impact on how well these backup air pumps function.
Consider utilizing two or more of these backup air pumps at once if your fish tank is large or the fish density is high.
What to Consider when Choosing a backup power supply for an Aquaponic System?
An aquaponic system need a dependable power source just as much as it does nutrients in the water.
Electrical equipment is common in aquaponics and serves a variety of roles that promote the health of an aquaponic system. Examples include lights, water pumps, and air pumps.Â
One of the most damaging failures in aquaponics, a power outage can essentially bring the entire system to a halt.
You would need to take a few factors into account before installing a backup system in order to adequately handle the event of a power outage.
Before installing an aquaponic backup system, you need think about things like
- occurrence of power outages
- length of the power outage
- necessary power output
- – Food is Grown All Year Round.-Food is Grown All Year Round.
- Because of the reservoir of water the plants and their roots must draw nutrients from, plants in aquaponics systems like Grow beds and Deep Water Culture (DWC) can survive for an extended period of time, frequently outlasting the length of a power outage.
- The plant containers are made to hold water in grow beds and DWC systems. So the plants can always get their nutrients from water even if the pump breaks down. During a power outage, the plants won’t perish thanks to this remaining water.
These kinds of systems can be used to safeguard the plants in the event of a power outage when designing an aquaponic system.
How do I Aerate my fish tank without electricity?
Perhaps not so for other kinds of aquaponic systems.
A maximum of 8 hours can be spent by plants in an NFT Aquaponics system. This is so that plant roots can’t continuously draw water from the NFT system to obtain nutrients for survival. The sump tank receives the water’s drainage, leaving the roots dry.
The plants will stay upright for two hours before the leaves begin to wilt, and then things will start to go south.
By having a backup air pump to keep the fish tank inflated during a power outage, fish can be kept alive. There are many different kinds of backup air pumps that, in the event of a power outage, deliver an uninterrupted flow of air.
The Penn Plax Silent Air and the Fulhengy Battery Aquarium Air Pump are the two pumps I’ve found to work the best.
You must take into account the fish tank’s size and the number of fish it is home to when selecting a backup air pump (fish density).
The effectiveness of these backup air pumps during a power outage can be significantly impacted by the fish density.
You may need to think about using two or more of these backup air pumps simultaneously if your fish tank is large or the fish population is dense.
A dependable power source is just as crucial as the nutrients in the water.
