Aquaponics Use Of Tank Water For Plants

Nitrate, the end product of an aquarium filtration system is also a main source of nutrients for many plants, even your good old garden plants and vegetables.
I am sure that the system could be made pretty much self sufficient but from a hobbyist point of view it would take some setting up to make the whole thing aesthetically pleasing. For experimental purposes though one could be set up in a car-less garage or large shed.
