An Overview: What Is Aquaponics?

Today is the era of urbanization and trend of apartments grows day by day. It also vanishes the trend of a backyard garden, so select an appropriate method to grow maximum food by using minimum space. Here in this article, I will tell you a complete overview of new technology named as aquaponics.

What is aquaponics?

The term aquaponics is formed by the combination of two words aquaculture and hydroponics which implies it combines the cultivation of fish within the aquarium and various plants in water. The essence of such a mixture is that the water circulation from the aquarium to grow bed and its purification through the hydroponics system while plants get the necessary nutrients. Since every system provides what the opposite system lacks, you may get both clear aquarium and organic food in your home.

Its definition says that it is a system of aquaculture which suggests feeding plants that you simply grow hydroponically by using the farmed fish waste products. In return, those plants purify the water in your aquarium. As result you can get a cheap, eco-friendly aquarium and production of food in cramped space at the same time.

It became a very popular method of cultivating plants in urban areas where there is no possibility of growing classical gardens. It is easy to establish so anyone can create and use this practical system and obtain higher food yield in their own residence.

What can be cultivated through aquaponics?

In an aquaponics system, one can grow several forms of vegetables counting on the kinds of fishes used, the pH of the water, temperature, and size of the aquaponics system. A number of the quite commonly grown plants are:

  • Herbs
  • Spring onions
  • Spinach
  • Radishes
  • Lettuce
  • Okras
  • Cucumbers
  • Cabbage
  • Broccoli
  • Tomatoes

Major key factor:

In the aquaponics system, whether small or large, one thing plays a vital role for both fishes as well as for the crops which also depend upon the ammonia value of the water. The fish create waste from the food they eat and it turns to ammonia.

Bacteria will convert that ammonia to nitrates during a grow bed or biofilter. If there are little or no bacteria within the system, the ammonia would not be converted to nitrates. Because ammonia is toxic to the fish and fish will eventually die.

How does aquaponics work?

Building an aquaponics system is not difficult but the most important challenge is to keep it running, after all, there are three sorts of living organisms within the water namely fishes, plants and bacteria. There are several varieties of components that are required to run the system properly. They are:

Environmental factor:

Before installing the system allocate the possible problems and find appropriate ways to beat them.

Humidity: Aquaponics could be a system with constant water flow through its two parts, count the natural evaporation rate and consequential increased moisture in your space. Also, increase the temperature in your aquarium. When the air within the apartment is cooler or there is poor air circulation, the temperature difference will cause extra humidity.

Water spillage: one of the important facts is that the aquaponics tank can also leak regardless of how careful you will be with water. Therefore, the area where you wish to form this method should be waterproof and without stuff that water can damage. Take great care with electric appliances you utilize near the aquarium. Be prepared beforehand for possible spillage.

Lighting: While the HIDs system spends plenty of energy, it proved to be the most effective to be used within the apartment.

Components of the aquaponics system:

To form an efficient system, you need to buy some essential components.

Aquaponics fish tank:

If you are a novice and wish to grow your plants during a small system, you will use a conventional aquarium. It is also possible by using tanks, tubs and barrels. A well-tuned professional aquaponics system implies one pound of fish per gallon of water. If you are just commencing to so that quite planting it is better to calculate 10 gallons of water for one fish.

Grow trays:

It builds the foundation of your future garden. Its size directly depends on the scale of your aquarium, simply you can cultivate as many plants as you have got fish within the aquarium. In the beginning, you will estimate one plant per fish.

Grow bed for plants:

It is actually a giant water-resistant container where you may grow your plants. You will be able to buy one or make it by yourself. The best grow bed could be a 6-10 inches’ deep wooden box lined with the sting of your aquarium and full of a chemically soil-free medium.

Grow media:

Its purpose is to produce support, drainage, and aeration of your aquaponics system. you will use perlite, coco coir, fine gravel or a combination of all three in equal proportions. Also, many folks prefer stones and clay pebbles because they are decorative.


You can use anything that is large enough to support your system, including concrete blocks, shelves or a table. The sole thing you must secure is to form a structure sturdy enough to support the grow bed.


You need them for returning filtered water from the grow bed into the storage tank. The foremost reliable systems are:

  • Ebb and flow
  • Bell siphons
  • Piping drains

Water pump:

They transport water from your tank to the grow bed. That’s way plants would not need for water because they are going to use aquarium liquid with the fish waste products filled with nutrients.

Also, it will transport filtered water from the grow bed to the tank which can allow this independent system to create a closed circle. For a completely self-sufficient system, you wish to put in a solar-powered pump. You need.

  • Water pumps which will make sure that water continually flows throughout your system
  • Air pumps which will provide oxygen to your aquarium


Some aquaponics system does not need a timer, but you must purchase one if you wish to install a bigger, more complicated and advanced design. Whether you utilize a basic timer or highly programmable one will rely on you and what variety of system you wish to put in.


The critical piece of hardware will provide an adequate amount of oxygen for your fish.

Best fish for aquaponics:

Without adequate fish, there are not any aquaponics system since they supply necessary nutrients for your herbs. Therefore, you wish to carefully select the simplest sorts of fish for your aquarium depending on:

  • The type of aquaponics system
  • Water temperature
  • The region you reside
  • The kind of plants you wish to grow

The most suitable fish for the aquaponics system are:

Tilapia: it is the foremost desirable tropical species for tiny scale systems. Thanks to their excellent rate, high tolerance to imperfect water conditions and harvestable size of one pound in six months.

Catfish: They tolerate cold climate, but detain mind that you simply must provide warmer water if you wish fish to develop properly and be healthy.

Yellow perch: it is a reasonably common species for aquaponics systems because they will place on growth at lower water temperatures.

Types of aquaponics system:

There are three most typical varieties of aquaponics system which might be installed for domestic as well as for commercial purposes. These systems are:

Nutrient film technique (NFT): this system is employed both in hydroponics and aquaponics. The water is enriched with the nutrients and flows through small gutters as an awfully thin film. On top of those gutters, plants sit in small cups in such the simplest way that their roots can touch the film and access the nutrients. This system is generally used for small vegetables, especially leafy in nature like lettuce and strawberries that have a small fibrous root system.

Media filled grow beds: This aquaponics system is that the simplest of all and is additionally suitable to grow vegetables with an even bigger root. During this system, the grow bed is stuffed with expanded clay or river rock medium through which the fish water is pumped either during a continuous flow or during a flood and drain cycle.

Deepwater Culture (DWC): This technique could be a commercial process where the plants are kept floating on the surface of the water in order that their roots can touch the water and absorb the nutrients from it. The foremost common sort of problem culture setup is when the fishes are reared in a tank and therefore the water is pumped out into the water channels on which floating rafts are founded with plants growing through them.

Advantages of the aquaponics system:

There are several advantages of using this technique.

  • Anyone can make this technique
  • There is an opening to style and install home aquarium aquaponics in every apartment regardless of how small it is.
  • It is a clean, closed system for growing both fish and plants
  • It saves water due to its reusing
  • It is a soil-free system and does not exhaust soil nutrients.
  • It does not use pesticides
  • It is an ecofriendly system and does not pollute the environment.
  • There is no waste
  • There is no fear of deforestation so as to supply new arable land.
  • It requires little work

Disadvantages of aquaponics system:

Along with the bright side, there is also some dark side of the system. here is some disadvantage of the aquaponics system.

  • Before the installation of aquaponics, a lot of know-how is required for this system.
  • This system is more complex to handle than hydroponics
  • It also required more space to functionally perform.
  • you also required proper feed for the fish.

Hopefully, through this article you get a complete overview of the aquaponics system.
