- Aquaponics combines aquaculture and hydroponics in a closed-loop system where fish waste fertilizes plants and plants filter water.
- The system is designed as a vertical, media-based continuous flow setup to save space, reduce leaks, and minimize energy costs.
- A 20-gallon tank and ~3 sq ft grow-bed keep the system compact and manageable for an apartment, supporting small crops like leafy greens and herbs.
- Key improvements include better drainage with a larger pipe, a quieter pump, higher grow light placement, and switching to black tubing to prevent algae.
- Lessons learned emphasize cycling the tank before adding fish, using a larger tank for stability, choosing resilient species like shrimp and feeder guppies, avoiding overfeeding, and engaging with local plant tank communities.
- The step-by-step build guide details materials, assembly, planting, cycling, adding life, and low-maintenance care, with total upfront cost around $663 and monthly energy cost about $14.
