When water from a fish tank is given to plants, they grow amazingly well from all the organic fertilizer from the fish wastes. And plant also do an amazing job at filtering these wastes out of the water and keeping the water healthy for the fish. In a system where water is recirculated between a fish tank and plant grow beds, the fish feed the plants and the plants clean the water for the fish.Home diy aquaponics systems are becoming more essential especially in today's society of product recalls appearing every single day for food. If you want to grow organic produce where you know exactly what has went into making it than this is for you.
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. commercial 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 regular agriculture as we know it, you till the soil, sow the seed and then maintain it by watering, fertilizing and weeding your garden or field. Eventually you harvest the hard earned produce.
If you don't want to wait that long, you can add nitrates to the water, but many organic gardeners don't want to add chemical fertilisers. That decision can be up to you. If you do decide to supplement the nitrogen, it will only be something to do until the system matures. After that you shouldn't have to do it again as long as you keep a good balance between fish and plants.
You have a container that the fish are in, the water from that container, either by pump or gravity, flows through the roots of the suspended plants. The plants absorb the nutrients (which sounds much better than they consume the fish waste even though that's what they are doing) which cleans up the water.
As a fish farmer raising healthy fish the prize will be well nourished plants as they have been raised on the fertilizer and food provided by the fish. As you properly care for your fish; the plants will flourish.
