The water is pumped back into the fish tank. Since the fish waste is consumed by the plants, filtration is greatly reduced which reduces cost. The fish waste is nutritious for the plants so you don’t need to add as much, if any, nutrients to the water for the plants. The cuttings from the plants can be fed to the fish if they are vegetarian like the Tilipia are which cuts down on feed costs.
Once the cycle is in motion, the farmer should not have to add any chemical whatsoever. The balance that is created between the plants cleaning the water and the fish polluting it will create the perfect chemical balance. There is a slight catch to this amazing process.
Catfish, carp and trout are similar to what tilapia is. They are great in producing eggs in temperatures of 68 degrees Fahrenheit similar to tilapia. They are easy to maintain since their food is inexpensive-in fact, they just feed on whatever they have in their environment. They are extremely fast growing in which they can multiply rapidly if they have enough excellent food to eat.
If you have ever had a fish aquarium, you probably know that a mechanical filter is required to keep the fish alive and the tank clean. But with an aquaponics system, the plants do all of that for you. Instead of a filter cartridge, a grow bed is used to pump water through and the plants roots do the cleaning.
This kind of system is ideal for growing plants in deserts. Since the water is given directly to the plants, instead of being dumped on the ground, water loss is minimal. Aquaponics can consume as little as 2% of the water as farming in the ground does. And since no soil is used, this is perfect for ares with poor soil or no soil at all. This has potential to allow many parts of the world to grow food that otherwise would not be able to.
In theory, all fish and in fact — all animals are suitable for such a system, because the toxins they excrete are a form of food for plants. Selecting a type of fish is based primarily on how much maintenance they require.
Some people like to have plants with the roots hanging directly in the aquarium, but this can be hard to do for most plants and can be unsightly and get in the way of lights. Roots can make good habitat for fish, but will also be eaten by some fish. A sometimes better way to grow plants with your fish water is to make a small hydroponic system where you pump the water into a grow bed and then allow it to flow back to the aquarium. You may be able to do this with your existing filter pump. And the way some filters are made, you can easily convert them to a grow bed.
A fish tank, this one is a no brainer. There is a lot to consider here since the size of the tank you choose affects how many fish you can have and how many plants you can grow.
One of the great advantages of aquaponics how to over traditional gardening is you don’t have to work on your hands and knees or bend over to work with your plants. That is if you locate your planting beds at waist level. So choose a comfortable level to place your growing beds.
Once you have your 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.
