Green Life Zen

Aquaponics is a form of farming that combines recirculating aquaculture with hydroponic nutrient film technique. One of crucial components of the system is an aquaponics fish tank. It incorporates the use of fish waste to create plant nutrients and natural filtration, rather than soil.

This system can be used to grow a wide variety of plants including leafy greens, herbs, veggies, fruits, and spices. Since the system relies on a closed loop, it allows you to grow plants year-round and they will never become tainted by soil.

Various Types of Aquaponics System

Before discussing about aquaponics fish tank we'll be discussing about some common types of aquaponics system first. There are lots of aquaponics systems you'll find out there and we'll be discussing 5 common types of them below:

1. Media Based Aquaponics System

This typical aquaponics system is usually made of plastic, fiberglass or PVC which are very light. The media may consist of river pebbles, pumice or gravel rocks. This media helps to increase the surface area that supports the roots, provide better aeration and prevents the roots from being buried in anaerobic material. For a recirculating aquaponics system, this media provides an environment that promotes good health for your fish and plants.

2. Nutrient Film Technique

The nutrient film technique (NFT) has become the most common type of hydroponics system. They are usually made of plastic or PVC using a thin stream of water which runs over a trough in which the plants are. This water contains nutrients that are absorbed by the roots, and is also used to aerate the roots.

3. Raft System

The raft system is another type of aquaponics system that is made of wood or plastic. The rafts help to keep the soil solid and provide additional structure for the roots. This helps to maintain healthy growth for your plants and helps to stabilize the water level and keep it from washing away.

4. Vertical Aquaponics System

Vertical Aquaponics System is the most efficient aquaponics system because of its high rate of production per square foot. However, it is not suitable for small spaces or people with a small budget. This kind of aquaponics system is usually made of PVC, plastic or wood and works well in the areas where there is a limited space available.

5. Media-less Aquaponics System

Media-less Aquaponic System lacks media, but instead uses rocks and gravel to hold the plants up allowing more water surface area to be exposed to the sunlight. The roots are usually suspended in the moving water which delivers oxygen directly to them just like plants growing in soil.

7 Essential Factors to Consider in Choosing an Aquaponics System Design

1. Location

Where you want to put your aquaponics system is most important. That is because the location of the aquaponics system could significantly affect the design and layout of your aquaponics system. For example, if you are planning to plant your aquaponics system in a small space where limited land is available, you should choose media-less aquaponics system to save on space.

2. Space

Space is also another factor that you need to consider when choosing an aquaponics system design. It will greatly affect the size of your fish tanks, the amount of fish and plants that can be grown in each tank, and how much water or nutrient solution you need for each tank.

3. Water Filtration

If you are planning to grow plants in your aquaponics system, you should also consider water filtration. Since the water in your aquaponics system will be reused again and again, it is important that it is completely clean before using it to grow more plants or fish.

4. Water Level Sensor

Since an aquaponics system uses bacteria to consume the fish waste for plant nutrition, if your water level sensor does not work properly and does not detect the correct water level, then those bacteria can die from starvation. This will affect the health of the entire system, so a working water level sensor is an essential feature.

5. Type of Plants

You should also consider the type of plants that you want to grow in your aquaponics system. It is important to keep in mind that different types of plants need different water and nutrient solutions. It is advisable to have a separate tank for each plant or group of plants.

6. Environment

The environment in which the aquaponics system is located can affect its performance. For example, if you have the aquaponics system close to the foundation of your house then it will not last long because of heat from the building. If you have a large area where you are planning to use your aquaponics system, then it is wise to have several systems so that each one will have a different location and an uncongested place in your garden.

7. Weather Conditions

The climate and weather conditions where you plan to use your aquaponics system can also affect its performance. In some regions and countries, there may be a certain season which is suitable for the growth of certain plants.

Exploring the Best Ideas of An Aquaponics Fish Tank

The following article aims to help you with the perfect ideas on how to choose or build an aquaponics fish tank that will suit your aquaponics system. We'll be discussing 9 crucial factors you need to consider before deciding to buy or build an aquaponics fish tank for your system.

1. Using Fish or Not?

The first decision you need to make is whether or not you will be raising fish in your aquaponics system. A common misconception that many people have is that the use of fish will end up contaminating their food crops. In reality, aquaponics pond or aquaculture systems are a closed loop system and cannot produce any sort of contamination nor can your fish eat plants. It is more likely that if your plants become contaminated, it will be from cross-contamination from other shared garden items such as dirt and mulch.

2. Hydroponic Sized Fish Tanks

In order to maintain the right water temperature and make sure your fish get the best growing conditions, you will want to make sure you have tanks that are big enough for the type of fish that you want to raise. In order to do this, it is recommended that aquaponics fish tank be around 50 gallons so you can maintain a steady temperature.

3. Water-efficient Bacteria

Another great thing about having your own aquaponics fish tank is that the water is recycled many times over, resulting in drastic water conservation next ot nothing waste! However, in order for this system to work correctly you will need bacteria. You can get the bacteria from any local pet store, or you can buy a bacterial starter kit which contains everything you need to make your own microbial cultures.

4. Aeration

Make sure to also add some type of aeration, such as a fountain or air pump, into your aquaponics fish tank. This will help to provide oxygen for your fish and prevent the water from becoming stagnant. The more oxygenated the water is, the healthier your fish will be and the more stable the ecosystem you create will be.

5. Decorations

One of the final things you will need to consider when it comes to an aquaponics fish tank is the decorations. Since this system is going to be creating an ecosystem for your fish, you want to integrate any decorative items that are in harmony with the environment. The most common decorations will be some sort of rocks, plants, or decorative plants . For example, if you use an aquarium then these may already come with a filter and a heater. This is because aquaponics uses water filtration as well as hydroponic cultures which both require filtration.

6. Temperature

So how do you set up your aquaponics fish tank? You will want to keep the temperature consistent to ensure your fish don't suffer from high or low temperatures. Therefore, if possible you will want to have a heater that is around the same temperature as their habitat, However, if you are using a home aquarium then this is not going to be possible, and so you will want to make sure that you heat the water on one side of your tank but keep it colder on the other sides. This is important because it makes sure that they are always at a steady temperature and prevents any possibility of flooding.

7. Lighting

Another important factor in this system is lighting. You will want to incorporate some type of lighting into your aquaponics fish tank even if you have an aquarium. This will help to keep your fish active and healthy by making sure they are getting enough rest, while also feeding them a good amount of light so they can continue properly metabolizing. The best thing to do is add a decorative light that is placed above the water level and make sure it is changed every day.

8. Water Quality

You will need to continually test the water in your aquaponics fish tank in order to ensure everything is going smoothly and there are no signs of contamination or sickness in your fish. If everything looks clean and perfect, you are ready to go. However, if there are any signs of the water being contaminated then you will need to change it immediately and start the cycle all over again.

9. Maintenance

When growing fish in an aquaponics fish tank, you will want to clean the tank often to make sure the habitat is always healthy and clean. You can do this by simply taking out your fish and using a hose or vacuum cleaner to make sure the habitat is clean. You will also want to check your pH levels at least monthly in order for your system to maintain its ideal balance. You will want to use purified water with no additives for this system because it can alter the pH levels if you add any other substances such as chlorine or bleach. If you have plenty of time, then you may wish to invest in an air pump so that you can make sure your water stays at its ideal pH level.


In conclusion, aquaponics is a great method of food production. It not only saves you time by allowing you to create a self-sufficient ecosystem for your fish to grow in, but it also saves you money because it is much less expensive than having your own conventional garden or farm.
