Science & Academy

Every calculation verified. Every system designed for resilience. From the nitrogen cycle to solar economics — then six certification tracks to teach you how to build and operate it all.

Part I · The Science
The Core Process
The Nitrogen Cycle in Aquaponics
Fish waste → bacteria → plant nutrients → clean water
FISH TANK 🐟 Rainbow Trout produce NH₃ waste NH₃ Ammonia BIOFILTER 🦠 Nitrosomonas NH₃ → NO₂⁻ (Nitrite) Nitrobacter NO₂⁻ → NO₃⁻ (Nitrate) NO₃⁻ GROW TOWERS 🌿 🥬 🌱 Plants absorb nitrates Roots filter & clean the water 1,884 grow sites · 36 towers CLEAN WATER Returns to fish · 90% less water use CASCADE AERATION 9 cascades · 24ft drop 85–92% DO saturation No electric aerators needed O₂ 9.6 mg/L @ 16°C
STEP 01🐟
Fish Produce Waste
Rainbow trout metabolize protein-rich feed, excreting ammonia (NH₃) through gills and waste. At 9–18 kg/m³ density, this provides abundant nutrients.
STEP 02🦠
Bacteria Convert
Nitrosomonas oxidize ammonia → nitrite. Nitrobacter converts nitrite → nitrate. K3 media provides 300–600 m²/m³ surface area.
STEP 03🌿
Plants Absorb
Nitrate-rich water feeds 1,884 grow sites across 36 towers. Plant roots uptake nutrients and filter water. Kalo loʻi provides natural polishing.
STEP 04💧
Clean Water Returns
Purified water cascades back through 9 drops (24ft total), gaining dissolved oxygen naturally via gravity. Uses 90% less water than soil farming.

TEMPERATURE
14–18°C
Sweet spot for trout
Site delivers passively via 6ft soil thermal mass. No chiller needed.
DISSOLVED OXYGEN
>7.0 mg/L
Critical for fish + bacteria
9 cascades achieve 85–92% saturation via gravity alone.
pH RANGE
6.8–7.2
Balanced for all organisms
Volcanic soil naturally buffers. Coral sand for fine-tuning.
AMMONIA (NH₃)
<0.5 mg/L
Toxic above 1.0 mg/L
Biofilter sized for 2× expected load. Alert at 0.5 mg/L.
Off-Grid Capable · Net-Zero Energy
Energy & Water Independence
Solar + rainwater + micro-hydro = resilient infrastructure
☀️
Solar PV Array
26 kW Peak
65 panels × 400W. ~143–169 kWh/day. Powers 3 houses, pumps, 10 printers, LEDs, cold storage. 40 kWh LiFePO₄ battery backup.
💧
Rainwater Harvest
~148K–180K gal/yr
4,000 sq ft catchment. Stored in 4× 2,500 gal IBC totes. Primary source for aquaponic top-up, irrigation, and humidity.
Micro-Hydro
~43W Continuous
18 GPM × 24 ft head × 53% Pelton efficiency. Small but runs 24/7. Powers IoT sensors independently.
SOLAR ECONOMICS — NET COST AFTER INCENTIVES Gross installed cost $56K–$74K Federal ITC (30%) −$16.8K–$22.2K Hawaii State ITC (35%) −$19.6K–$25.9K NET: ~$19.6K–$25.9K ← 65% combined tax credit savings Payback: 5–7 years vs HECO rates ($0.38–$0.45/kWh) · Then free energy for 20+ years
