Aquaponics is one of the latest techniques that enable you to have a self-sufficient food supply. It is a sustainable system that is simple to understand and easy to maintain. It is borne from two traditional approaches, aquaculture and hydroponics. What’s great about aquaponics is that it eliminates the disadvantages of these traditional approaches. In a nutshell, aquaponics is a way to maximize the benefit of fish tank water, instead of wasting it like aquaculture does.
Although the pH range for the plants is different, what is acceptable for the plants does fall inside the acceptable pH level range for the fish. In fish aquaponics system there needs to be a compromise between the pH level for the fish and the plants. The lower end of the pH range for the plants is much more acidic than for the fish. Having the pH of the water reach the lower end of what is acceptable to the plants, should never happen, if you are monitoring the pH of the water with the fish in mind.
Choose an elastic tub for your fish. It is very useful to have an elastic tub for the fish where one can improvise its windows or holes for the tubing.
aquaponic works by pumping water from a fish tank to a separate grow bed where the plant roots grow directly into the fish water. This can be done in a medium like gravel or clay balls, or with the roots just hanging free in the water. The plants are supplied with all the water and nutrients they need, so growth can be spectacular. And this method is all organic, so vegetables that are grown this way are typically of garden grown quality.
Growing an aquaponics garden can supply you with a low cost supply of the most fresh and nutritious food you can get. How can you get food that is more fresh than what you can pick out of your back yard or even your living room? This is a great way to make yourself food independent. Not only will you always know where your food is coming from, you will also have some of the most healthy food available.
Once you have your an aquaponics system up and running, you will have a tank which holds the fish (possibly Tilapia) and a growing bed that the plants are in. In the fish tank, you will have a species of freshwater fish in one to 2,000 liters of water. The fish create waste and so does the uneaten fish feed. This waste creates ammonia.
The choice of fish for your Aquaponic system is very important. If you plan to only feed your family, then the type of fish they like most would be preferable. The only factor you need to adjust is the fish to plant ratio so the correct amount of nutrients will be provided the plants. The plants will also have to be able to clean the water so the fish will have a suitable environment to live.
The nutrients needed for your plants, in some cases can not provided all by your fish. You have to supply them with the respective essences, if the quantity is lower than what the plants need. In most cases you will need to add iron, calcium carbonate or potassium carbonate.
