The Benefits of Aquaponic Gardens

Fish live under water but they still need to breathe, and like most animals, they need oxygen to survive. Aquaponic gardens can give you lots of fresh vegetables and tasty fish. They are great for any type of home, as well as for people of any age and whatever occupation you may have.

The major process in aquaponics is aeration. If the water is properly aerated, then your fish will be happy and your plants will grow normally. On the other hand, if the water is not properly oxygenized, then there is very little chance that your farm will survive for more than a couple of days. 

However, they do not take care of themselves! It is true that they require very little care, but it is essential that you give them those few minutes a day, each and every day, in order to obtain good results and keep the farm producing for a long time.

How Does Aquaponics Work?

The reasons why aeration is so important are quite simple and easy to understand. First of all, the dissolved oxygen is necessary for the fish to breathe.

Even though the fish live under water they still need to breathe, and just like most other animals, they need oxygen to survive. When they lack oxygen they die, thus the balance from your aquaponic system is lost and in a matter of days your plants will start to get yellowish and eventually die also.

In addition, fish excrement will decompose and be transformed from toxic ammonia into useful nitrates in the presence of oxygen. Thus, if the water is not properly aerated, the fish poop will not be transformed, the plants will have nothing to eat, and the poor fish will die intoxicated with ammonia. That is not a very pleasant prospect! You gotta learn to do it right.

This is why you will have to monitor the quality of your water each and every day, at least at first, and have a back-up plan in case the power goes off and the air pumps quit working. This is the best way to take care of your aquaponic system and make sure it works for a long time. And your plants and fish will thank you!

How Do You Make an Aquaponics System?

 You may be wondering how to make an aquaponics system to grow your own food at home.

How to Make a DIY Indoor Aquaponics System

Aquaponics is a method by which you grow plants and nurture aquatic animals together in a system that recirculates the nutrients produced, to the benefit of both plants and animals. The aquaponics approach is gaining in popularity as a sustainable gardening method and if you're curious to try it out for yourself, there are some great hacks for building your own system. This article is one such example using commonly available components from IKEA and a few extras from your local hardware store. The system looks good enough to keep in your living room or bedroom, just to keep your family happy!

Steps

Setting up the frame

1. Visit IKEA to purchase the frame. You'll need the Antonius frame from IKEA for the main frame. It will be combined with one or two wire baskets and two of the plastic containers. Use the 50 litre container for the fish tank at the bottom, and the 25 litre container for the growbed at the top. Assemble all the parts based on the accompanying packaging instructions.

If you can't find the frame at IKEA, ask around to see if friends have a spare one, or make a request on a site like Freecycle. 

2. Use the wire basket as support for the 25 litre plastic container that will house the growbed. It is not strictly necessary to have the 50 litre plastic container fish tank at the bottom if you just put the container on the floor. You may want to trim the plastic lip on the top container to ensure a better fit; in this tutorial, the handles have been cut off the ends of the container as well. However, this is not strictly necessary. To cut the plastic, use a small saw or some standard wire pliers. 

3. If you want to personalize the system to fit in with your home decor, now is a good time to do it. The photo shows an example of a fish tank that has been decorated with a strip of PVC plastic sheet:

Plumbing Part 1: The standpipe The plumbing for the aquaponics system is not too complicated and you can rely on a few basic principles to help make the system as efficient as possible.

1. Use a small 600 lph (litres per hour) electric submersible pump in one corner of the fish tank which takes the water up to the growbed. The water flows through the growbed and exits in the opposite corner to which it entered. As the water then flows back to the fish tank, it pushes any solid waste over towards the pump, ready to pulled up into the growbed.
   • Use a bypass ball-valve on this system. This item diverts some of the water from the pump straight back into the fish tank. This lets you control the amount of water going into the growbed, and the diverted water also creates some water movement in the fish tank, as well as providing additional aeration. In this tutorial, 13mm PVC pipes were used throughout. Initially, it's recommended that you too start with the growbed and the siphon used here.
2. Obtain male and female threaded adapters. Drill a hole in the right place in the growbed––you need to make sure that the female adapter will fit between the wire mesh squares. Make the hole about 6 or 7 centimetres (2.3-2.7 inches) from the edge of the container in each direction; the hole should form a snug fit with the threaded male adapter.
3. Place the male adapter through the top of the growbed. Then fit a rubber O-ring onto the threads. Next, screw the female adapter onto the male adapter until you have a nice snug (and waterproof) fit. You can add some silicon to the bottom if you want to, but it's not strictly necessary. Finally, use a reducer on top of the male adapter. The one shown here is a 25mm to 13mm reducer.
   • This whole piece is called the standpipe and this is how the water will exit the growbed. You want the overall height to be about 1 inch (2.5cm) under the top of your growbed media; thus, you will need to cut the pipe down so that it is the right height for you. At this point, let the silicon dry if you have used it.

Plumbing Part 2: The bell siphon and media guard The bell siphon is a very effective method of slowly flooding the growbed and then draining the growbed quickly. It does this with a non-mechanical action, and has no moving parts to break.

1. Observe the 25mm-13mm reducer on the far left of the photo shown below. This is where the water will exit the growbed.
2. Place the 60mm bell siphon in the middle. This is a 60 mm piece of pipe with an airtight cap on the top. The pictured bell siphon shows some pieces cut out of the bottom as well as some holes drilled in the side––you want these holes to be no higher than about 1 inch (2.5cm) from the bottom of the pipe. The water will drain down to this level and will then stop.
3. Finally, the 100mm media guard, shown on the far right, is simply to keep the growbed media out of the bell siphon. This has holes drilled or cut out of it to allow the water to come in––and to keep the roots and the media out! The cap is optional, but helps to keep things out of the bell siphon.
4. Bell siphons can be tricky to get working. The mechanics of a siphon is relatively complicated, but you are really only concerned with the practical application of siphons to allow you to quickly empty a growbed into either a sump tank or fish tank using a simple mechanical method with no moving or electrical parts.[1]

Plumbing Part 3: The ball-valve bypass

1. Add the ball-valve by-pass. This whole setup allows you to control how much water flows into the growbed and so it's an important addition. The ball-valve bypass also allows you to divert some water back to the fish tank, providing additional aeration and water movement into the tank. This improves the health of the fish.[2]
   • In the picture below you can see the small 600 lph (litres per hour) pump with a small piece of 13mm pipe coming from it. This then has a T-Bar attached and then the 13mm pipe continues up to the 90 degree elbow at the top, which empties the water into the growbed. Coming off the second part of the T-Bar is a simple ball-valve that controls the flow of water that is diverted back into the fish tank.

Finishing up

1. Once you have all the framework, the containers, and the plumbing set up, add water into the fish tank and start the pump up. Test to see if everything works properly, and to see if the system is watertight!
2. Fill the top container (the growbed) with some sort of growing media. This could be hydroton, lava rock, perlite, river stones or other similar matter. Use something that allows the water to flow through the growbed and is non-toxic.
3. Once this has been done, you are ready to add the fish and to start putting plants into your system. Initially, add only a couple of small fish, just to start producing the ammonia needed to kickstart the system.
4. Read up on aquaponics for more details. Setting up your system is just the beginning––you'll need to keep learning more about the use and benefits of the system to make the most of it. As such, it's recommended that you check out additional information on how to actually run your system and to gain a thorough overview in how aquaponics works properly. You can search for more resources online, purchase books about aquaponics or visit your local library to request further information.

Warnings

• Make sure that all your plumbing is pushed together tightly in order to avoid any leaks. The systems shown in this tutorial are not glued as a firm push is usually sufficient!

With Aquaponics It's Easy to Grow Your Own Vegetables

Aquaponics gardening is quickly becoming very popular. Why? Growing your own crops can be a demanding task even for those in love with gardening. It is a time consuming activity and it requires lots of energy and dedication. In addition to that, a traditional garden requires fertile land which will sustain your efforts of growing some crops.

These are the main reasons for which many people give up their dream of growing their own vegetables and switch from organic food. What most people do not know is that there is a way of growing organic food (pesticide and chemical free) in the comfort of your home. Yes, you read it correctly: inside your house.

This new type of farming is called aquaponics and is the simplest way to become a farmer! The best part is that you will not only grow vegetables, but you will also grow fish, so that you can offer your family a diversified and healthy diet. It all starts quite simply, with a plain tank filled with water in which you place some fish. You can go for Chinese Catfish, Crappie, Bluegill or Koi, or whatever species of fish you want to grow in your house.

Put them in the water, take good care of them and in about a month, put in some seeds so that they can reach the water and get the nutrients from it. The plants will develop and start growing with the nutrients offered by the fish. In the meantime, the fish will enjoy a clean environment as the plants will act as “maids” for them, cleaning and refreshing their water each and every day. 

As you can see, this type of farming does not require any type of land, fertilizers or chemical substances. Just set up the system and make sure that the water has the normal PH so that the fish will live comfortably in there. Then, let nature follow its course!

You can grow almost anything you want in aquaponic farming. Leafy greens, fruity plants and legumes can all be planted in the aquaponic farming. If you have a piece of land where you cultivate ground-based plants (potatoes, carrots, asparagus, onions, garlic and so on) you can use this water to water those plants and the results will be spectacular!



Nothing can compare to the easiness, safety and great results of aquaponic farming! You have everything you need at hand, without too much effort and what is even more important, without using any chemical additives to your crops.
