The document describes a rotational aquaponic system using a drip field surface. It explores different surface designs like serpentine channels, parabolic punches, and pooling to maximize aeration and water flow. The chosen design uses parabolic punches that rotate on a hinge, allowing the surface to fully rotate and aerate the water through thousands of tiny bubbles rather than large bubbles. This rotational concept aims to simply and effectively aerate water for aquaponic systems.
