Fish. Roots. One living system.
Follow the full system—from viable fish and measured feeding to biological filtration, water balance and healthy crops.
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 →Fish & feeding ↗
Compare viable species, source stock, acclimate fish and manage feed and biomass.
Choose viable fish: temperature, feed and purpose
Compare six practical fish groups, then narrow them by your actual water conditions and a verified hatchery plan.
Interactive tool · 6 min + guided practice →Fish & feedingFeeding, biomass and stocking
Use fish mass and actual feed intake as operating inputs, with capacity checked independently.
Interactive tool · 6 min + guided practice →Cycling & water balance ↗
Nitrogen conversion, oxygen, alkalinity, pH, solids handling and feed-to-plant balance.
Balance fish feed and planted area
Turn feed grams per day into a transparent area comparison, then check the biological and hydraulic limits.
Interactive tool · 6 min + guided practice →Cycling & water balanceFishless cycling: prove the biofilter works
Establish nitrification with a known input and repeated measurements before stocking.
6 min + guided practice →Cycling & water balanceWater quality: pH, ammonia and alkalinity
Track the interacting measurements that govern fish, roots and nitrification.
Interactive tool · 6 min + guided practice →Cycling & water balanceSolids removal and biological filtration
Separate particle collection from dissolved nitrogen conversion and design maintenance access into both.
6 min + guided practice →Plants & growing media ↗
Choose crops, support roots and manage plant nutrition without compromising fish.
Operation & resilience ↗
Commissioning, daily care, health observation, power failures and operating costs.
Oxygen and outage resilience
Measure oxygen where it matters and rehearse a recovery plan before fish depend on it.
6 min + guided practice →Operation & resilienceFish health, quarantine and daily operation
Prevent avoidable introductions, observe fish before symptoms escalate and keep records useful for diagnosis.
6 min + guided practice →Original teaching models and worked examples, with extension and manufacturer sources where applicable. Independent specialist review is pending. Numerical tools verify accounting equations; they do not certify a crop recipe or fish system.
