Aquaponic Fish Tanks

Let us talk about fish tanks or home for your fish in an aquaponic system. There are several choices for fish tanks just like there are for grow beds in fish tanks and you are going to hear a common theme amongst all of them.

First is that you have to start with food safe materials using polyethylene, or fibre glass or always optimal materials as you know that you are going to perfectly fine with any of those.

Stock tanks

Lets us also talk about rubber made stock tanks. These are the tanks that you will see in pastural land used for watering cattle. You can find these at feed and grain stores and these work really well as fish tanks.

IBC Container

Another option is IBC (Intermediate bulk containers) totes These are the liquid storage containers that are used for shipping all around the world. They work very well as fish tanks. Just make sure you know what was stored in that tank before using it as a fish tank. It should have been food or food safe material.

55 gallon drums

Same thing with storage barrels, these 55 gallon drums. They would work just fine. You can also use batch tubs as a fish tank. Those work very well and they are pretty fun. You are rescuing them from the garbage dump.

Other containers

Really any sort of container you have or even a hole in the ground that is lined with pond liner will work as a fish talk as well. Dura skrim liner is organic and food safe and hence the best liner for a fish tank.

Make sure you get a tank high enough, so your children or pets cannot get into it. You are going to get the most stability in your aquaponic system somewhere around 200-gallon mark. This will give you less fluctuation in temperature and less fluctuation in pH when you go for a bigger tank, so it is going to be a little easier for you. Round shaped tanks are the best to have as they are the most optimal. The reason for that is that the water can circulate, the fish can circulate and most importantly for our purposes, the solid weight can be kept suspended. It is not going to settle in pockets or corners of the tank and create anaerobic conditions.

More surface area

The next thing is surface area. If you have a choice between tanks that are lower and wider, that is going to be better than a tank that is narrower and taller. The reason is you want to optimize the surface area on top of your tank because of oxygen exchange.

Let us talk about coverings now. Fish do not need light. Fish like to have some covering and some shade because it helps them feel secure. They do not like a lot of people looking in their tank. You also want to keep it covered at the very least, so they do not jump out. Fish will jump out as they are going after bugs, or they may think life is better on the other side of the tank. Fish nets work really well and should be secured so they do not slip off. Fish nets are also nice as you can feed the fish.

Remember about the ratio of your fish tank to the number of grow beds. It is about 6 gallons of water per square foot of growing space.

So, here it is – the amazing world of aquaponics – combining fish farming and hydroponics creating a symbiotic atmosphere. Just take note of the pointers for picking the right fish tank as mentioned in this article and you should be good to go.

Using Trout in Aquaponics

Creating the Aquaponics system is very fun. Getting the right fish is one of the key steps. To find out what fish species should be stored in your pond, you must first ask what your intentions are to keep them. If you grow fish to eat, you can choose a different species than the one you just fed. The type of fish that is used in aquaculture in aquaponics is usually a variety of fresh water. These include tilapia, catfish, trout, perch, Oscars, koi and goldfish.

Trout in Aquaponics

The trout is one of good Aquaponics fish, which manages well only in cold water. It has an excellent flavor and is excellent for cold areas where it experiences winter for months. To grow well, this species needs uncontaminated water. Cultivation of this species means that you must choose the right plants for growth in the substrate because most aquatic plants prefer a warmer water temperature. However, they are growing very fast because they have a very high conversion rate and eat very well. They are carnivores, so you have to feed them with commercial pellets. They can develop a tendency to cannibalism where they eat their own species of fish or others.
There are three important elements you need to set up a good trout aquaponics system: fish, plants, and bacteria. Fish are necessary to survive organic vegetables; the plants avoid the toxicity of the water with ammonia, nitrates and other types of waste, and the bacteria ensure that the plants absorb the necessary nitrogen from the water.

The choice of fish

The most exciting part of this process is choosing the fish for your aquaponic system. First, you must decide if you want the fish to eat or show a purpose. Regardless of whether you use an external or internal system, you will have a wide range of fish to choose from.

If you live in an area with climate change and need food for aquaponic fish, it is best to choose one that survives in different seasons. trout aquaponics are a popular option for cooler weather you are not interested in these options, the tilapia fish is also a good option for any aquaponic system, regardless of its size. Keep in mind that most of the best-known freshwater fish are ideal for aquaponics.

The decision on the amount of fish that will be placed in the holding tank will depend on the filtration system; Available space and amount of vegetation that the system can handle.

Let’s take a closer look at these elements.

To get the right vegetation, you should consider some things, such as the amount of fish in the tank; the amount of food added per day, as well as the maturation, size, and weight of the fish.

If you have a simple design, such as raised beds, aquaponic fish systems with one square meter of vegetation, then you will need a minimum of sixty grams of fish feed per day. You need at least a hundred grams if you have demanding plants, like pumpkin.

It should be remembered that the plants are completely dependent on fish waste, as well as the remains of fish feed. The shortage of fish waste can stop the development of vegetables since the water will have a minimum level of useful nitrates and organic matter. On the other hand, an excessive amount of food can end up poisoning or killing fish. It is very important to find the right balance for fish survival and aquaponic vegetation.

Guide To Building A DIY Indoor Aquaponics System

With the depletion of agricultural land for farming and the introduction of Genetically Modified (GM) crops, it’s necessary for us to produce our own herbs and vegetables in the absence of sufficient land space for cultivation.

Do you want to know the simple solution to this?


The rise of DIY indoor aquaponics has enabled gardeners to grow plants by fertilizing them with waste water from fish in a closed system.

Aquaponics is a combination of aquaculture, which involves growing and breeding of fish, and hydroponics, which refers to cultivating plants in water without soil.

Building your own aquaponic garden is a revolutionary way to grow organic vegetables, greens, herbs, fruits while using fresh fish as a great source of protein.

Materials Needed

We have to choose the right materials in building our aquaponic system. Here they are:

  • 20 Gallon Aquarium. For example, Tetra 20 Gallon Complete Aquarium.
  • Industrial grade heavy duty shelving.
  • Plastic storage tote.
  • A water pump like Homasy 80
    GPH Submersible Water Pump.
  • 4 feet of inch silicone tube to attach to the water
  • 2 inch ball valve to attach to the silicone tube.
  • 10 feet of inch PVC pipe.
  • Four inch PVT T’s.
  • Three inches PVC L’s.
  • Three inch PVC end caps.
  • Two inch PVC threaded female ends with male plugs.
  • Two inch bulkhead fittings.

How To Build Our Aquaponics System

First, test your water pump to be sure it works and pump it at the height you need. Also, make sure you have the right size fittings for each of your materials.

Cut down the pipe pieces and drill holes into the end caps to assemble the siphon. Drill hole into the grow bed container so you could fit the bulkhead fittings and the PVC pipes through.

Rinse your aquarium gravel thoroughly before using it.

Set up the tank without water and start working on your grow bed. The tubing that comes from the aquarium pump should go into the grow bed about 1-2 inches under the top layer of growing media. It’s advisable that the top layer of the grow media be a dry layer.

When you do that, the siphon will kick in when the water rises to its level, and it will suck down the outflow pipe back into the aquarium. Place a PVC at the end of the pipe to increase suction. The water will be brought up again by the pump and the cycle will be repeated.

Some aquaponic systems perform a full cycle every 5 minutes.

The ball valve on the tube is to control the pump speed. If the water goes too fast, then the siphon won’t stop siphoning and the grow bed won’t be filled with water. You might need to make some adjustments to get it

Start Enjoying Your Aquaponic Garden

Now that you’ve set up an aquaponic system, you can start enjoying healthy, safe, fresh and delicious foods all year round.

Aquaponic systems are purely organic. They are 4-6 times more productive and use 90% less water than conventional gardens. Did I forget to mention that there’ll be no need for weeding or fertilizing?

Eat and stay healthy with your aquaponic garden.

Benefits of growing plants using Aquaponics

What is Aquaponics

The combination of growing plants and fish together is called aquaponics. This procedure is used for growing soil fewer plants. Both fish and plants are grown in one integrated system so that space can be saved easily while growing plants. If plants and fishes are kept together, the fish waste is used as food for the plans and the plants don’t need other food to grow up. As the plants naturally filter the water, the fish can also survive well in the system.


Using the fish nutrients the aquaponics pa provides necessary nutrition to the plants which are required for their survival and growth. If the proper procedure can be followed in the right type of environment, the plants can be grown faster than the normal procedure of growing plants. Different types of material can be grown easily and successfully following this procedure. In this article, I am discussing few benefits of aquaponics method.

1)    Requires small space

For the space management of your home, this option is one of the greatest options to check out this time. Many people don’t have much space on the outside of their home. So, they can grow plants using the aquaponics. Some plants don’t need much light to grow. You can easily grow these type of plants with this method.

2)    Plants grow quickly

If you want to grow plants faster, you should go for the aquaponics fish nutrients method. In this method, the plants grow faster than the usual method. On research, it has been found that aquaponics can grow plants four times faster than the usual. So, you can get your plants mature and grown up in a very short time.

3)    Grow variety of plants

If you think you will get to grow a very limited number of plants with this method, you are wrong. You will be able to grow a wide range of plants with this process. Starting from the flowers, the fruits, and vegetables, everything can be grown in an aquaponics garden. So, if you want to grow various options in your home garden, you can consider the option.

4)    Convenience

The process of aquaponics can be controlled easily. On the whole procedure, there is no soil included. So, using this method, you can easily grow different kinds of plants. As the aquaponics work in varieties of plants with less effort, so it is one of the convenient options to grow plants.

So, these are few benefits of growing plants using aquaponics. Though there are some drawbacks with this method like controlling the temperature, water low, PH balance and so on, still you can manage everything and grow different plants easily on your home garden.
