Aquaponics and fish keeping as a hobby are two totally different things. Yoshi was saying that his plants get all of their nutrients from the fish food and waste, where I don't see how that would be possible with a lot of aquarium plants like dwarf hair grass, dwarf bbts, etc.
That's possible and it's been done. Diana Walstad has proven scientifically that all the nutritients plant need can be obtained through fish food. You just need to read the label of the food and put enough of it in the tank, have substrate that has caution exchange capacity(ability to store nutritients for future use),have critters that process the food faster so it doesn't rot around(like snails, shrimp, etc) and the substrate is small enough for plants to root but big enough for those "nutritient" particles to settle in between the subsrate and not fly around the tank for example.

I have one tank that I dose daily and one tank setup Diana Walstad method and I can assure you it's million times easier to look after the Diana Walstad type tank, or should I rather say I just don't do anything at all to it. Doesn't cost me extra money on ferts too.
Regardless, the question wasn't about what's easier, but what's possible.

The drawback to a Walstad tank is you need specific plants and fish loading. So in that sense it is very limiting. But if the challenge of doing it calls one, then go for it. It has never appealed to me.
