By combining the design for EggPOD, we have the 3D drawing for PeachPOD. First look at two screenshots…
Some touchups need to be done, for example, beside showing fish water in the fish pool, a vertical hose should be installed, sucking and sweeping fish poop up, as the carousels spin slowly, giving all plants uniform sunlight exposure. A self-primed in-line water pump can be installed beneath the bottom of the lower carousel. The vertical hose turns horizontal to guide water to drop into a circular gutter around the bubble duct:
The grow sand beds need to have some slopes according to this filtered water flow path so that the filtered water can drain back to the fish tank along the inner wall of the Torus:
Finally, the following shows the flow path of bubbles within the double layer cavity:
