How To Build An Aquaponics System? (Step By Step Guide)

Building an aquaponics system is a great way to create your own organic food garden, and it’s very simple to do. The aquaponics theory includes three types of living things that complement each other in a closed, recirculated water body: (1) aquatic animals, (2) bacteria, and (3) plants.

Aquaponics is a system of water-soaked plants and fish that creates food in a continuous cycle. One benefit to aquaponics is that it uses anaerobic digestion, which can reduce organic waste by breaking down the organic material into carbon dioxide, water, and energy.

The article will guide you on how to build an aquaponics system.

How To Build An Aquaponics System: Step By Step

The majority of the nutrients transported by the water come from dissolved fish excrement, which microorganisms then transform into nutrients for plant growth.

One or more fish tanks, a sedimentation unit or clarifier, substrates for the development of bacteria or appropriate biofilters, and a hydroponic system for plant growth make up the fundamental components of an aquaponics system.

A closed water cycle is created by the pipes that connect these components. After mechanical and biological filtering, it is common to utilize a pump sump (also known as a single pump or single loop system), which pumps water back to the fish tanks after which it flows naturally to the hydroponic system.

Figure: A typical aquaponic system has a sump where the water is pumped or flown back to the fish tanks and flows by gravity with the components, as well as a fish tank, sedimentary, biofilter, and hydroponic unit.

Steps for build an aquaponics system;

Step 1) Figure Out Questions

First figure out the four factors that are important when choosing tanks, pumps, and fish. These 4 queries will help you construct an effective aquaponics system that serves you for years to come. Think carefully before you answer each question below.

  • Why are you doing this?
  • Where will your system be located?
  • When do you want to get started?
  • Who will be administering your system?

Step 2) Plan The System

Planning your aquaponics system is essential to ensure it meets your needs and produces the quality products you desire.

There are a few key things to keep in mind when planning your aquaponics system, including:

  • Size and layout of the system
  • Type of water source and filtration
  • Fertilizer type and dosage
  • Propagation method for plants
  • Temperature requirements for fish and plants

Step 3) Prepare Size and Layout of the System

Select the system page layout based on the location of the system and the other answers you chose.

The size of your aquaponics system will largely depend on how many plants you want to grow, as well as the size of your tank or container.

The layout of a typical aquaponic system includes four parts: the fish tank, the grow bed, the water filter, and the water pump.

The Fish Tank

Aquariums can be used to house fish in an aquaponics system. Aquariums should be at least twice the size of the fish you plan to house. The water in an aquarium will provide adequate oxygen and nutrients for your fish.

Consider what type of fish you would like to keep in your aquaponics system. Some popular choices include tilapia, goldfish, and koi. Make sure the tank is large enough for the number of fish you plan to keep.

The Grow Bed

The grow bed is where you will plant your vegetables and fruits. You will need to purchase a grow bed.

A grow bed is essential for growing plants in aquaponics. It provides the necessary space for plants to grow and sends nutrient-rich water directly to them from the fish tank.

Water Pump

A water pump is one of the most important components in an aquaponics system. It’s responsible for moving water around the system and distributing it evenly to all of the plants and fish.

A good water pump will flow a lot of water, but it shouldn’t be too noisy or vibrate too much. It should also be able to withstand high temperatures and humidity levels.

If you’re looking to build an aquaponics system yourself, make sure you buy a good water pump before you start construction.

Water Filters

Water is an essential component of an aquaponics system. Aquaponics systems rely on water to provide a steady stream of nutrients to the plants, as well as to clean and cool the fish and vegetable tanks.

In order for an aquaponic system to work properly, it is important to have enough water available at all times.

If the water level in the tanks falls too low, the fish will start to die and the plants will become stressed. By monitoring water levels, you can ensure that your aquaponics system is running smoothly.

Aquaponics, or water-filtration-based agriculture, is a type of farming that uses recirculating aquatic systems to grow crops in a symbiotic relationship with bacteria and fish.

Aquaponics systems require regular maintenance to ensure the proper function of the water filter and other components, as contaminants can easily penetrate the system.

Water filters are an important part of any aquaponics system and should be replaced on a regular basis to maintain cleanliness and performance.

Replacing a water filter not only helps to remove impurities and pollutants from the water but also helps to eliminate offensive odors.

Step 4) Setup Biotic Components of An Aquaponics System

There are many different biotic components that make up an aquaponics system, and the list can vary depending on the size and configuration of the system.


Fish are a key component of aquaponics systems. Fish provide food for the plants, and the plants clean up the fish waste. Aquaponics systems can be used to produce food in both indoor and outdoor settings.

Aquaponics systems use water and fish as their two main inputs. The water is circulated through the system in order to provide nutrients and oxygen to the fish.

The fish excrete waste which is then captured by the plants and converted into organic matter. This organic matter can then be used as fertilizer for the plants.

There are several different types of fish that can be used in an aquaponics system. Some of the more common types of fish include tilapia, catfish, goldfish, and koi.


Aquaponics is a type of aquaculture that integrates plants and fish into an efficient production system.

In indoor setups, aquaponic systems are often used to produce fresh vegetables and fruits. Outdoor setups are more commonly used to produce seafood, such as salmon or tilapia.

Step 5) Regular Monitor the Aquaponic System

In this system water recirculates through the system, providing nutrients for the plants and returning waste back to the water.

It’s important to keep track of the system so that you can make sure it’s running smoothly.

Regular monitoring can help ensure that all components of the aquaponic system are functioning properly and helping to produce food safely and efficiently.

Final Words

Aquaponics is a type of agriculture that combines aquaculture, or raising aquatic organisms such as fish, with horticulture, or cultivating plants in water. In an aquaponics system, the fish provide food for the plants, and the water circulated through the system helps to keep everything healthy.
