Aquaponics systems employ sump tanks as a critical component to ensure optimal water levels, enhance aeration, and safeguard fish health.
These tanks, featuring a 1:2 ratio of fish tank to grow bed, collect water drained from the grow beds and return it to the fish tank. Consequently, the water level in the fish tank remains constant, irrespective of the levels in the grow beds.
The inclusion of sump tanks enables increased plant production without necessitating additional fish tanks, thereby fostering a healthy aquatic environment for the fish.
Although not indispensable for small-scale aquaponics designs, sump tanks prove advantageous in larger systems, facilitating the management of water level fluctuations.
Commonly used designs include CHOP/CHIFT PIST and CHOP 2, with the former being a simpler option suitable for beginners and the latter offering greater system expansion potential.
The incorporation of sump tanks can ultimately enhance the overall success of the aquaponics system, plant productivity, and fish well-being.
The Basics
In the context of aquaponics, sump tanks serve as additional tanks with a 1:2 fish tank to grow bed ratio, preventing low water levels in the fish tank when providing water to multiple grow beds and collecting water drained from the grow beds to maintain water height in the fish tank.
The installation process of sump tanks involves locating them at the lowest point in the system for water flow. It is crucial for the sump tank to hold or handle the total volume of water in the grow beds, which is approximately one-third of the grow bed media volume.
The benefits of sump tanks in aquaponics include:
- Allowing for increased plant production without adding new fish tanks
- Preventing negative impacts on fish health due to low water levels
- Maintaining the correct water levels in the fish tank.
Benefits and Function
One critical aspect in the aquaponics system is the incorporation of an additional tank that serves multiple functions to enhance the overall efficiency and productivity of the system. The sump tank in aquaponics offers several benefits and drawbacks, as well as maintenance requirements.
Benefits of a sump tank in aquaponics include:
- Prevents low water levels in the fish tank when providing water to multiple grow beds.
- Collects water drained from the grow beds and pumps it back to the fish tank, maintaining water height regardless of grow bed levels.
- Improves aeration and dissolved oxygen levels for the fish, creating a healthy aquatic environment.
- Allows for increased plant production without the need for additional fish tanks.
However, there are some drawbacks and maintenance requirements to consider when using a sump tank. These can include the need for regular cleaning and monitoring of water levels, as well as the potential for clogging or blockages in the system.
Despite these considerations, a sump tank can greatly improve the success and productivity of an aquaponics system.
Design Options
There are various design options available for incorporating an additional tank into an aquaponics system to enhance its efficiency and productivity. When considering a sump tank design, two popular options are the CHOP/CHIFT PIST and CHOP 2 systems.
The CHOP/CHIFT PIST design utilizes a water pump in the sump tank to continuously push water to the fish tank and grow bed. This design is simpler and is suitable for beginners, as it helps maintain water levels and provides a healthy environment for the fish.
On the other hand, the CHOP 2 design uses a dual loop system to simultaneously send water to the fish tank and grow bed. This design allows for easier addition of more grow beds in the future, making it suitable for expanding aquaponics systems.
Both designs have their pros and cons. The CHOP/CHIFT PIST system is simpler to set up and maintain, while the CHOP 2 system offers more flexibility for future expansion. Ultimately, the choice of sump tank design depends on the specific needs and goals of the aquaponics system.

Frequently Asked Questions
What are some common challenges or issues that can arise when using a sump tank in aquaponics?
One common challenge when using a sump tank in aquaponics is the risk of clogging or blockage in the system, requiring regular maintenance strategies such as cleaning filters and checking water flow to ensure optimal functioning.
How often should the water in the sump tank be changed or refreshed?
The water in the sump tank should be changed or refreshed as needed, depending on factors such as water quality, nutrient levels, and fish health. Regular monitoring and testing can help determine the appropriate frequency. Sump tanks provide benefits such as maintaining water levels and improving fish health.
Can a sump tank be added to an existing aquaponics system, or does it need to be planned from the beginning?
Adding a sump tank to an existing aquaponics system is possible and offers several advantages. It can help regulate water levels, improve fish health, and accommodate the addition of more grow beds in the future.
Are there any specific considerations or requirements for the location of the sump tank within the aquaponics system?
Considerations and requirements for the location of the sump tank in an aquaponics system include positioning it at the lowest point for water flow, ensuring it can hold the total volume of water in the grow beds, and providing easy access for maintenance and monitoring.
What are some alternative methods or strategies for maintaining water levels in the fish tank without using a sump tank?
Alternative methods for maintaining water levels in the fish tank without using a sump tank include automatic water level sensors and manual water top ups. These methods provide a practical solution to prevent low water levels and ensure a healthy aquatic environment for the fish.
