Want to get into aquaponics but don’t know how? It’s easier than you might think. Aquaponics is a sustainable gardening method that combines hydroponics and aquaculture.
Hydroponics refers to growing plants in nutrient-rich water without using soil, while aquaculture refers to raising fish in tanks or ponds.
Soil is not required for an aquaponic garden: instead, food scraps are used as fertilizer for plants without the need for fertilizer runoff into waterways like traditional farming would require.
|Fish Tank||Holds fish and acts as the source of nutrients for the plants|
|Grow Bed||Where plants are grown and the water is filtered|
|Water Pump||Circulates water between the fish tank and grow bed|
|Air Pump||Oxygenates the water for the fish|
|Air Stone||Diffuses air into the water|
|Plumbing||Connects the different components of the system|
|Growing Medium||Provides support for the plants and aids in filtration|
|Fish||Provide nutrients for the plants|
|Plants||Absorb nutrients from the water and purify it for the fish|
The water tank is the most important part of your aquaponics system. It needs to be large enough to hold the right amount of water for your fish and plants, but small enough not to take up too much space in your yard or home.
Materials used for a tank include plastic, metal, concrete and fiberglass. The material you choose depends on how big you want your tank to be as well as what will work best with the type of fish that you’re raising and where they live most comfortably (they need a specific temperature range).

A composting toilet is, in my opinion, the best way to go for your aquaponic garden. There are many reasons for this:
- Composting toilets use no water and very little electricity.
- They produce no odor, unlike a septic tank or outhouse (if you’re into that sort of thing).
- They don’t require any maintenance except adding more sawdust or peat moss every so often and replacing an occasional lightbulb if it goes out.
Biogas is the name given to a mixture of gases produced by anaerobic digestion. In an aquaponic system, as waste breaks down in the fish tank, it forms anaerobic conditions. As such, biogas is created and can be collected for use elsewhere in your home.
There are many benefits to having a biogas system installed in your aquaponic garden:
It’s renewable energy – you’re essentially turning garbage into fuel!
It’s cheap! You can purchase materials from any hardware store or online retailer that sells aquaponics supplies; most systems require only simple tools and materials that you already have on hand (like PVC piping).
The end product is super-clean burning natural gas (methane) which can be used for cooking or heating water. You’ll never need another gas bill again!

Fertilizer is an important component of aquaponics and it must be used correctly in order to avoid harming the fish or plants.
There are many types of fertilizer available, but organic fertilizer is the best choice for your aquaponic garden. To make your own organic fertilizer you will need:
- A compost pile that has been allowed to decompose for at least a year
- Worm castings (you can purchase this at a garden store)
- Organic matter such as leaves, grass clippings, etc…

Fertilizer pumps are an important part of your aquaponics system. These pumps move water from the fish tank to the root zone, where it will be broken down by bacteria and absorbed by plants.
Fertilizer pumps work either by moving air bubbles that carry food particles or by moving fluid (usually water) with dissolved food particles in it.
The type you need depends on whether you use solid fish food or liquid fish feed, as well as how much space you have available for a pump.

Integrated Pest Management (IPM)
Pesticides are bad for you, the environment and the fish. Integrated Pest Management (IPM) is a better alternative. It’s a proactive approach to pest management that includes biological, cultural, physical and chemical controls.
You can use pesticides if you wish, but it’s best not to expose yourself or your family to them unnecessarily. Instead of using pesticides (which are toxic to humans), try these other methods:

System monitoring software
Aquaponics is a complex system, and you’ll need to keep track of a lot of information. Your software can help you do this.
Track water levels, nutrients and pH so that you always know what’s happening with your system.
Use the software to identify problems in your system before they get out of hand, or even before they happen at all!
For example, if the plants are showing signs of nitrogen deficiency but there’s plenty of nitrogen in the water (a common problem), this will be picked up by the monitoring software and highlighted for you to deal with immediately rather than waiting for it to become critical until it becomes too late for corrective action.
Finally, managing an aquaponic garden involves many variables – from temperature control through lighting cycles through plant growth cycles through nutrient levels – all these factors have an impact on one another which should be monitored regularly so that changes can be made quickly when necessary
Outside run-off tent
The outside run-off tent is a very important part of your aquaponic garden. The tent keeps the water clean, it keeps the fish safe and it protects them from predators and other dangers. It also makes sure that no pests get into your system and eat your plants or nibble on them until they die.
As you can see in this diagram, the tent has two openings: one for adding new plants to the system (this is usually done at planting time) and another one for removing finished plants from it (usually at harvest time).

Pruning and root control
Pruning and root control. The first step in aquaponic garden maintenance is pruning. You should be cutting off any leaves that are not healthy or growing properly, as well as any dead, diseased or damaged roots.
These should be removed from the system to prevent them from spreading disease or molding into other plants’ roots.
Once you have completed this process, you can cultivate your crops more effectively by removing all but one of each plant (if it has multiple heads) and spreading them evenly throughout the system so that each plant gets equal access to nutrients and water.
Soil testing is important. There are a number of reasons it’s important, but the most obvious one is that you need to know what nutrients your plants require and how much of them are present in your soil. This will help you decide what kind of fertilizer to use and how much to apply.
Soil testing at home can be done with a simple test kit from any hardware store or garden center.
The test kits come with instructions on how to take samples and send them off for analysis by an independent laboratory (the cost ranges from $10-$20). The results will tell you everything you need to know about the pH balance, nutrient content, organic matter levels and more.

If you want to start an aquaponic garden, it’s important that you know about all the different components.
You should also be familiar with the most common problems faced by those who have already taken this route.
By doing so, you will be better equipped to create your own system and avoid potential pitfalls along the way.

What is aquaponics?
Aquaponics is a sustainable farming method that combines aquaculture (fish farming) with hydroponics (soilless plant cultivation) in a closed-loop system. Fish waste provides nutrients for the plants, which in turn purify the water for the fish.
What are the benefits of aquaponics?
Aquaponics offers a number of advantages over traditional farming methods, including higher yields, lower water usage, and reduced environmental impact. It also allows for the cultivation of both fish and plants in a relatively small space.
What can you grow in an aquaponic system?
Aquaponic systems can be used to grow a wide range of plants, including leafy greens, herbs, tomatoes, and strawberries.
How much does it cost to build an aquaponic system?
The cost of building an aquaponic system can vary widely depending on factors such as system size, equipment quality, and the types of plants and fish being grown. A small-scale system for home use can be built for a few hundred dollars, while larger commercial systems can cost tens of thousands of dollars.
How often do you need to change the water in an aquaponic system?
Water changes in an aquaponic system are typically only necessary when levels of harmful compounds such as ammonia or nitrite become elevated. Depending on the size of the system and the number of fish and plants, water changes may be needed as often as once a week or as infrequently as once a month.
