Above is the system last week, below is the system when we set it up in late march.
And here are the fish that make it possible - our silver perch. They're native fish to Australia and are found in the Murray/Darling Rivers.
We want to be as self-sufficient in our food production as we can be and this system helps enormously with that. After the initial setup it's so easy to garden! There is no watering, weeding or fertilising like there is in our soil garden - it really is a lazy garden. I just wish we'd done it sooner.
