From selecting the appropriate fish and plants to managing water quality and nutrient levels, this guide will walk you through the essential steps to setting up and maintaining a successful aquaponic system.

What is Aquaponics and How Does It Work?

Aquaponics is a sustainable food production method that combines aquaculture (raising fish) and hydroponics (growing plants in water). In aquaponics, the waste produced by fish is converted by the beneficial bacteria into nutrients that plants absorb. The plants, in turn, filter the water for the fish. This creates a closed-loop system that uses 90% less water than traditional agriculture and can produce fish and vegetables in a small space all year round.

In an aquaponic system, the fish and plants work together in a symbiotic relationship where the fish waste provides the necessary nutrients for the plants to grow while the plants filter and purify the water for the fish. The result is a self-sustaining closed system that requires very little maintenance.

Benefits of Aquaponics

Aquaponics is becoming increasingly popular among farmers, gardeners, and sustainable food enthusiasts worldwide because of its many benefits. Here are some of them:

  1. Sustainability: Aquaponics is a sustainable method of food production that uses less water than traditional agriculture and does not require harmful pesticides or chemicals. It is an environmentally friendly method of growing that can help reduce the impact of food production on the planet.
  2. High Yield: Aquaponics can produce a high yield of both fish and plants in a small space. Plants grow faster in aquaponics systems because of their constant access to nutrients.
  3. Fresh, Nutritious Produce: Aquaponic systems can grow a variety of fresh produce that is high in nutrients and free from harmful chemicals. Because the plants grown in aquaponics are free from fertilizers and other chemicals. 
  4. Reduced Water Usage: Aquaponics uses up to 90% less water than traditional agriculture because the water is recycled through the system.
  5. Easy to Maintain: Aquaponic systems are relatively easy to maintain once set up. Because the system is self-contained, it requires less work than traditional agriculture and can be managed with minimal effort.
  6. Educational: Aquaponics is a great tool for teaching children and adults about sustainable agriculture and the importance of environmental stewardship. It can also be used to teach science and math concepts related to biology, chemistry, and physics.

Aquaponics is a sustainable, efficient, and environmentally friendly way to grow fresh produce and fish. Its benefits make it an attractive option for farmers, gardeners, and sustainable food enthusiasts who want to reduce their environmental impact while producing high-quality, nutritious food.

Setting Up Your Aquaponics System

Setting up an aquaponic system may seem overwhelming, but with proper planning and preparation, it is a straightforward process. Here are some key considerations when setting up an aquaponic system.


Aquaponics System

Things to Consider Before Starting an Aquaponics System

If you're planning to build your aquaponics system or purchase a complete system, it is essential to consider these things. 

Personal Considerations

1. Choose an aquaponics system that you want to implement.

You can choose between media based systems, raft systems, NFT systems, or a combination of these systems.

2. What are the goals and purpose of your aquaponics system?

Why do you want to have an aquaponics system? What plants or fish are you planning to grow and raise? Are you going to eat your fish? These questions should be given thought to plan your system correctly and know what method will meet your goals and purposes.

3. Are you a do-it-yourself (DIY) person?

Are you a do-it-yourself person, or do you prefer to purchase a well-proven, free-made design? This is one of the essential considerations in planning your aquaponics system.

DIY Aquaponics is trial and error but can be a rewarding and fun learning experience. It may also take a long time to make as you try to figure things out yourself. However, if you want a proven system that can run quickly and with technical support, you can purchase a free-made aquaponics system.

Environmental Considerations

1. Humidity

In an aquaponics system, the water flow is constant, so you must consider the natural evaporation and increased moisture in your space. The temperature difference will cause extra humidity.

2. Water Spillage

Your fish tank or aquarium can leak. Therefore, the area where you want to create your system is an area that can get wet.

3. Lighting

Plants need light to grow. All plants require sunlight for photosynthesis, which converts light, oxygen, and water into carbohydrates (energy). Plants need this energy to produce, bear fruit, and bloom. 

Sunlight is the best source of light for plants in an aquaponics system. However, if you decide to grow an indoor aquaponics system, you can use artificial light to supplement your plant's light needs. Artificial lighting needs to be considered and carefully selected because plants absorb wavelengths at either end of the light spectrum, which we cannot see.

B. Type of Aquaponics Systems

The three main types of aquaponic systems: are media-based, raft system, and nutrient film technique. Another is the hybrid system which is a combination of the three main types of aquaponics systems. Each has advantages and disadvantages, so choosing the one that best fits your needs and space requirements is essential.

1. Media-Based Systems

These are the most common and popular types of aquaponics systems. In this system, plants are grown in a medium, such as gravel or expanded clay pellets, that provides a surface for beneficial bacteria to break down fish waste and turn it into nutrients. The water is then returned to the fish tank.


Media Based Aquaponics System

2. Raft Systems

In this system, the plants are suspended in rafts on top of the water in the fish tank. The roots of the plants dangle in the water, and the beneficial bacteria break down the fish waste, providing nutrients for the plants.


Raft System

3. Nutrient Film Technique Systems

This system involves a constant flow of nutrient-rich water that passes through the roots of the plants. The plants are grown in channels, and the water is then collected and returned to the fish tank.


NFT System

4. Hybrid Aquaponics System

A hybrid aquaponics system combines multiple types of aquaponics systems. Most commercial aquaponics uses a hybrid system because of its efficiency and great use of space. One example of a hybrid system is a combination of raft and media based systems. 



Hybrid Aquaponics System

C. Location and Space

Here are some key considerations when choosing a location for your aquaponic system:

  1. Access to natural light: Plants require adequate light to grow, so choosing a location that receives sufficient natural light or sunshine is essential. If you plan to set up an indoor aquaponics system, consider installing grow lights to supplement natural light.
  2. Temperature: Choose a location where the temperature can be regulated. Consider installing a heater or air conditioner to maintain a consistent temperature.
  3. Water source and drainage: Your aquaponic system will require a constant water supply, so choose a location near a reliable water source. It is also essential to ensure that there is adequate drainage to prevent water from accumulating around the system.
  4. Electrical outlet: Your aquaponic system will require an electrical outlet to power the water and air pumps. So choose a location near an outlet or consider using an extension cord to reach a nearby outlet.
  5. Ventilation: Proper ventilation is vital to prevent the buildup of humidity and to ensure that there is adequate airflow for the plants and fish to thrive

By carefully considering the above factors, you can choose a location for your aquaponic system that is well-suited for the needs of your fish and plants.

D. Materials Needed

To set up an aquaponic system, you will need several key materials. Here are some essential materials required to set up an aquaponic system:

  1. Fish and plants - You will need fish and plants to complete your aquaponic system. Choose fish and plants that are well-suited for your climate and the size of your system.
  2. Fish tank - The fish tank provides a home for the fish, and the water in the tank is circulated to the grow bed, where it provides nutrients for the plants. Choose a tank size based on the number and type of fish you plan to raise, and ensure it is made of a durable, non-toxic material such as food-grade plastic or glass.
  3. Grow bed - The grow bed is where your plants will grow. Choose a size that fits the available space and is appropriate for the number and type of plants you plan to grow.
  4. Plumbing system - The plumbing system circulates water from the fish tank to the grow bed and back. It includes a water pump, tubing, and fittings to create a continuous water flow. A siphon or overflow system can also be used to regulate the water level in the grow bed.
  5. Water pump - The water pump is responsible for circulating water from the fish tank to the grow bed. Choose a water pump that is appropriate for the size of your system and has a flow rate that can support the needs of your plants.
  6. Air pump - An air pump is used to oxygenate the water in the fish tank, which is essential for the health of the fish.
  7. Tubing and fittings - Tubing and fittings are used to connect the various components of the aquaponic system, such as the water pump, air pump, and grow bed
  8. Grow media - Grow media provides a surface for beneficial bacteria to grow. Common grow media include gravel and expanded clay pellets.
  9. Aerator and Air Stones - Are used in the fish tank and media beds.
  10. Grow Lights - Optional. This is mainly used in indoor systems.
  11. Heater - Optional. Using a water heater will depend on your location, fish species, and target water temperature.
  12. Monitoring System - Optional. It depends on your situation and how you want to manage your system.
  13. Timers and Controllers - are mainly used for lighting, pumping, and controlling the temperature.

Fish and Plants Selection

Selecting the right fish and plants is crucial for a successful aquaponic system, as these are the two main components of an aquaponic system. These two components create a symbiotic relationship, with the fish providing nutrients for the plants and the plants filtering and purifying the water for the fish.

When selecting fish for your system, it is essential to choose fish species that can thrive in the specific conditions of your system. Some popular fish species for aquaponics include tilapia, troutcatfish, goldfish, and koi. These fish species are hardy, easy to maintain, and provide a good source of plant nutrients.

The plants that you choose for your system should also be carefully selected. Ideally, you should choose plants that are easy to grow, are suitable for the conditions in your system, and provide a good source of nutrition for you and your family. Some popular plants for aquaponics include lettuce, spinach, tomatoes, cucumbers, and herbs like basil and mint.

Water and Nutrient Management

Good water quality and nutrient balance are essential for the health of your fish and plants and the productivity of your system. 

A. Cycling Your System

Cycling your aquaponic system establishes a healthy balance between the fish, plants, and bacteria in your system. When setting up your system, it is vital to allow the necessary bacteria to establish and begin breaking down the waste produced by the fish. 

B. Water Quality Management

Maintaining good water quality is essential for the health of your fish and plants. There are several factors to consider when managing water quality in your aquaponic system:

  1. pH Levels: pH levels should be maintained between 6.5 and 7.5 for optimal plant growth and fish health. Regularly test the water to ensure pH levels are within this range.
  2. Ammonia Levels: Ammonia is a toxic waste product produced by fish that can harm the health of the fish and plants in your system. Monitor ammonia levels regularly and take action to reduce levels if they become too high.
  3. Nitrate and Nitrite Levels: Nitrate and nitrite are essential nutrients for plant growth but can also be toxic to fish if levels become too high. Monitor nitrate and nitrite levels regularly and take action to reduce levels if necessary.

    C. Nutrient Management

    Fish waste provides the nutrients needed for plant growth, but ensuring that nutrient levels are balanced and sufficient for optimal plant health is essential. Here are some critical considerations for nutrient management:

    1. Understanding Nutrients: There are three primary nutrients that plants require for growth: nitrogen, phosphorus, and potassium. These nutrients are found in fish waste and can be supplemented as needed.
    2. Testing Nutrient Levels: Regularly test nutrient levels in your system using a nutrient test kit. This will help you determine if nutrient levels are balanced and sufficient for plant growth.
    3. Supplementing Nutrients: If nutrient levels are too low, or if certain nutrients are not present in sufficient quantities, it may be necessary to supplement with additional nutrients. This can be done using a variety of commercial nutrient supplements or natural methods, such as adding compost or worm castings to the system.

    System Maintenance

    System maintenance is essential for your aquaponic system's ongoing health and productivity. Regular monitoring and cleaning are necessary to ensure the water quality remains optimal for the fish and plants and the equipment correctly functions.

    A. Monitoring and Adjusting Water Levels

    One of the vital maintenance tasks in an aquaponic system is monitoring and adjusting water levels. This is especially important as the water evaporates and is taken up by the plants. You will need to regularly top up the water level to ensure it remains at the appropriate level for your system.

    In addition to adding water, you may need to adjust the water level to maintain proper water flow and oxygenation. This can be done by changing the drain height in your grow bed or adding or removing water from the fish tank.

    B. Cleaning and Maintenance Schedule

    Regular cleaning and maintenance are essential for your aquaponic system's health and productivity. Here are some essential maintenance tasks to include in your schedule:

    1. Cleaning the fish tank: The fish tank should be cleaned periodically to remove any accumulated waste or debris.
    2. Cleaning the grow bed: The grow bed should also be cleaned periodically to remove debris or excess waste. This can be done by removing the plants and washing the grow bed with a hose.
    3. Checking for pests and diseases: Regularly check your plants and fish for signs of pests or  diseases. Take action immediately if any issues are detected to prevent them from spreading.
    4. Checking and maintaining equipment: Regularly check and maintain your pumps, filters, and other equipment to ensure they function correctly. Replace any damaged or worn parts as needed.

    By incorporating these tasks into your regular maintenance schedule, you can help ensure that your aquaponic system continues to function at its best. Your system can provide a sustainable fresh produce and fish source with proper care and attention.
