Or over the fields growing the pasturage that feed the livestock we eat.
The fish waste is broken down and used by the plants just as they are in your planted tank. All part of a grand bio-chemical equation that is as natural as.. well... pooing.
I suppose that idea doesn't gross me out nearly as much as chemicals fertilizers. However, I can't believe most human poo is very good for anything, considering what most of us eat. I read somewhere that having some of that bacteria inside of us was actually good, but I can't remember the source.
While we're on the subject, does anyone know where the dry ferts we buy online come from?
Do a search for Aquaponics and there's all kinds of info about growing food and fish together, and eating both.
We have been doing that. I just thought I would ask the wonderfully creative people who use this site.
While waste water and sludge is legal to use on non food crops in the US it's not legal on food crops in many places. Why? Because products like Milorganite can contain heavy metals like cadmium among others. There is a bill here in FL to start using treated sewage on fruit crops but only from septic tanks. Not 100% sure about the other states though.
I find it astonishing what IS legal to use. If pesticides kill things, why should we be spraying them on our food, that we eat, to.. you know.. live? All we need to do is make sure the plants get what they need. They will naturally ward off pests and diseases. Like red grapes: They will produce resveratrol that help us ward off diseases as well. But they only produce it if they are exposed to fungus. The same company who made the pesticides also made nerve gas and other deadly chemicals like agent orange for war. They just altered it a bit so they wouldn't waste their efforts after the war was over and decided we might as well spray it all over our food. The same people working for that company, also work in the FDA, Dept. of Agriculture, etc., so, it's no wonder how it is legal. People just put their faith in their govt. and....
Well now I'm just ranting..
I oddly had a photo of someone who had a tomato plant growing out of their filter.. Not sure what I did with it though, sorry.
its ok, i'd heard of people putting plants in their HOB filters. I do that to give my propagated houseplants a head start, but I don't think this is done the same way.
awesome! thank you!
