System designs
Raft, media-bed and channel growing, with connected fish, treatment and return systems.
Fish. Filters. Roots.
Explore the living system between a fish tank and a growing bed. Separate water movement from waste handling, biological filtration, and the needs of the plants.
14 min + model exploration →System designsMedia-bed aquaponics: grow without hiding the waste
Design an accessible aggregate bed, verify flood and drain behavior and preserve its biological function.
6 min + guided practice →System designsRaft, NFT and decoupled aquaponics
Compare the plant side of the system while keeping fish treatment requirements visible.
6 min + guided practice →System designsChoosing a fish tank for aquaponics: materials, working volume and access
Compare a tank by its intended use, serviceable layout and actual water inventory. Separate container capacity from the biological capacity of the complete system.
