Are you interested in having fresh, organic healthy fruits and vegetables, even FISH, being at your complete disposal in your OWN HOME???
Well, you have come to the right place! Welcome to the Aquaponics Systems site!
Why is aquaponics an excellent and easy solution for a healthier and natural life? Because…
- Aquaponics system gives you the opportunity to consume fresh organic fish, fruits, and vegetables from your very own home!
- Your system can provide you up to 50Kg of fish and hundreds of kilograms of vegetables within 6 months!
- Building your own aquaponics system is relatively simple and easy
- It doesn’t require a lot of physical space in order for it to work efficiently
- Aquaponics system is a real money saver- both by its design and its maintenance (i.e. you will need to use only 1/10 the amount of water compared to classic farming)
- It is easy to find aquaponic systems enthusiasts both locally and around the world. They will be a great support network to you when you decide to take your first step
- Αquaponics systems are adjustable systems. You can adjust them anytime you like, and can be added on to increase your harvest
Aquaponics Systems the Idea
The Idea of aquaponics systems came from a combination of Aquaculture and Hydroponic Systems. It proposed to be the best solution for both the negative sides for both Hydroponics and Aquaculture:
Disadvantages of Aquaculture
Aquaculture re-circulating process is about getting the excess nutrients out of the system, which is usually happening daily, by getting a percentage of the water out. As a result, we have water which is rich in nutrients, that need to be disposed of and clean fresh water replaces it.
Disadvantages of Hydroponics
To feed the plants the hydroponic system needs a constant supply of expensive nutrients. Due to flushing the systems on a regular basis a waste disposal issue appears.
Aquaponic Systems are the magical solution for the downsides of both aquaculture and hydroponics. Thinking about re-circulating both systems together we will find that the negative aspects of aquaculture (‘getting the excess nutrients out of the system’) is the best solution for the negative aspect of hydroponics (‘the hydroponic system always needs expensive nutrients’) and no more wasting water because of the periodic flushing of the systems. This means no more lost money. By the magical touch of aquaponic, we will have fresh fish, vegetables and fruits all the time in the cheapest and cleanest way possible.

Aquaponics Systems Stages
We feed the fish normally and then the fish extract ammonia into the water
The pump lifts the water from the fish tank up to the grow-bed
The water drips down through the porous media bed / filter, passing through the roots of the plants before discharging back into the tank
The plant’s roots absorb the water and nutrients that they need to grow, this purifies the waste out of the water. The fresh and clean water that the fish need then returns back to the tank
Aquaponics System Nitrogen Cycle
Ok, now since we have covered the basics, let’s have a closer look at the roots of the aquaponics plants. Are they making use from the fish tank water as it is, or are there hidden secrets behind the aquaponics system success?
The answer is no, there are hidden soldiers working unceasingly backstage for the ultimate success of the system so let me introduce you to the grow-bed bacteria.
I know most of us when we hear ‘Bacteria’ (or ‘Germs’ according to the disinfectant commercials) we interpret that they are meant to be bad, right? Aren’t they? The answer is no, and like everything else has its good and bad, this kind of bacteria is actually very useful. We can call it the main soldier in aquaponics system.
Ammonia to Nitrite:
Normally, fish excrete ammonia and it’s harmful for the fish (causes major damage to kidney tissues and gills, decreased resistance to disease, weak growth or even death). Decomposing food also creates ammonia. Fortunately, on the surface of the grow-bed media, there are Nitrosomonas bacteria, which eat the ammonia and get out nitrite (this nitrite has a much less negative effect on the fish than the ammonia, but still the case has some problems in that it stops the fish from taking up oxygen).
Nitrite to Nitrate:
Fortunately, there are other good bacteria, called “Nitro-bacteria”, which eat the nitrite and give out nitrate.
Plants and Nitrate:
Nitrate happens to be the best food for the plants, which makes them grow very quickly; in order that the plants roots absorb the nitrate and the water in order to grow faster than in any other system.
Fish and Fresh Water:
After plants have absorbed all the nitrates, fresh water is returned to the fish tank. This is what we call “Aquaponics System Nitrogen Cycle” which is the real technique made by the Aquaponics; a real technique for the most efficient system that produces fresh fish and organic (vegetables / fruits) to every house; and can be turned easily into your home business as well.
Aquaponics System Grow-bed Media
If you are experienced with hydroponics you are OK. There is no difference between the normal way of growing plants and the Aquaponics System. The grow-beds can be filled with media such as expanded clay pebbles, gravel, vermiculite, perlite, and many other things can be used as media to grow the plants, even floating foam rafts that sit on the water surface.
Aquaponics Systems Fish
A high number of fish can be grown in an aquaponics system fish tank. Many kinds of fish can be bred in Aquaponics systems such as Tilapia, White bass, Crappies, Trout and many other species. Generally we can say it is a very productive fish growing system. Choosing the fish you will be growing depends on many factors. All of the necessary information is in our Aquaponics Fish help guide.
Aquaponics Systems Plants
A common question that beginners always ask is, “Which kinds of plants can I grow in an aquaponics system?” We can say that all vegetables and herbs can be grown in the aquaponic farming with no exception, many kinds of fruits also; but choosing the vegetables or fruits that you will be growing in your aquaponics system will be elaborated on later with further details in the aquaponics gardening area.
Aquaponics Systems Forms
Aquaponics systems differ in form from one system to the other. They can be as simple or as complex as you like. Let’s see how below:
