Mosman backyard, Sydney. Railway sleeper aquaponic growbeds, pond with cascade currently stocks 70 silver perch, which will be plate size this season. The four growbeds are filled with 10mm river gravel and lined with EPDM rubber pond liner. The pond holds about 2000L and is sunken 500mm into the ground, providing thermal mass and reducing temperature fluctuations. Not only does this system look attractive, but has also supplied an abundance of herbs and vegies in a previously overgrown and disused part of the yard.
