- | Aquaponics combines the two systems in a symbiotic environment. It cancels the negative aspects of each. Instead of adding toxic chemical solutions to cultivate plants, Aquaponics uses highly nutrient effluent from fish that contain virtually all the nutrients needed for optimum growth of plants. Instead of discharging water, Aquaponics uses plants to cleanse and purify the water, after which the water is put back in the aquarium. This water can be re-used but must be topped up at certain stages due to losses from evaporation and plant usage. | ||

* Fish are fed and then produce excrement rich in nitrogen (ammonia NH3 and urea), phosphor and potassium. This excrement is the source of nutrients for the plants. Food given to the fish is put back into the water in the form of fertilizer (excrement) but the ammonia is toxic for the fish. We must filter the water to reduce/rid of the ammonia so the fish will survive. | * Fish are fed and then produce excrement rich in nitrogen (ammonia NH3 and urea), phosphor and potassium.

There are basic components that every Aquaponics system will need, regardless of the type of Aquaponics system we set up. There can be some variation in what we actually use for each component, usually dependant on how much money we want to spend. we will need the following for an Aquaponics set-up. | There are basic components that every Aquaponics system will need, regardless of the type of Aquaponics system we set up.

These are the basic components we will need when we set up our Aquaponics system but what we end up using depends on the type of system we decide on. It is advised to start small so we can learn the art and science of Aquaponics before investing too much time and money. As we gain experience, we can add more tanks and grow the size of our Aquaponics garden and move up to miniature farms. | These are the basic components we will need when we set up our Aquaponics system but what we end up using depends on the type of system we decide on.
