How to keep and breed Koi fish and Goldfish

DIY Aquaponic Systems Yep you read it right, this gardening technique uses fish poo to fertilize your garden and grow your food 4 times faster than conventional methods. Not only that, this new method of gardening doesn't use any soil what-so-ever which mean NO WEEDS! Wohoo! "I've just built my own  DIY Aquaponic Systems . It was simple and it looks and works just like the ones that cost thousands more." Aquaponics  is the combination of  Aqua -culture, (raising aquatic animals such as fish), and Hydro- ponics , (growing plants without soil). Fish waste is recycled into nitrates which feeds the plants and the plants clean the water for the fish. When the plants are well watered and well fed using this method, they will often grow twice as fast as those grown in soil. And because we're not using soil, the roots don't need to dig very deep to find water and plants can be grown close together using much less space. Formal scientific interest...
