Home & Garden Garden DIY Aquaponics: Building a Vortex Filter (Video) By Sami Grover Writer The University of Hull University of Copenhagen Sami Grover is a writer and self-described “environmental do-gooder,” now advising community organizations. our editorial process Twitter Twitter Sami Grover Updated October 11, 2018 Migrated Image Share Twitter Pinterest Email Garden Urban Farms Planting Guides Indoor Gardening Insects From a video roundup of DIY aquaponics to an Aquaponics Made Easy DVD, we've explored plenty of resources for backyard enthusiasts of aquaponics—a term used for the symbiotic combination of hydroponics and fish farming. But, often, the process can still be pretty confusing if you don't have plumbing experience. Luckily, there are folks like The Urban Farming Guys who are ready and willing to share their experiences—and here they walk us through how to build a vortex filter which, they say, would cost US$4000 in a store, yet can be made for $100 with a little ingenuity. Much like their previous how to video on how to build a DIY anaerobic digester for biogas production, these urban homesteaders—who abandoned suburbia with 20 families for inner city farming instead—are refreshingly down to earth in their instructional videos. Not only do they show you what parts go where, but they walk you through the trouble shooting they've had to do themselves. I'd be lying if I said I was ready to take on my own aquaponics system just yet. (Hey, I have to figure out how to keep my tomatoes alive first!) But I am glad that there are folks like these who not only share their experience in DIY green tech—but do so in a way that makes sense for us less practically minded TreeHuggers out there. Check out the Wiki, forums, projects and resources on The Urban Farming Guys' website for more how to information on cleaner, greener and homegrown food, energy and more.
