Water flows from your tank through the system. Plant roots absorb nutrients as they grow. Clean water returns to the aquarium.

Simple circulation. Natural balance.

Diagram illustrating an aquaponic filtration system with five steps: 1. Fish produce nitrogen-rich waste; 2. Bio-filter breaks down ammonia into nitrates; 3. Nitrate flows through plant roots; 4. Plants absorb nitrates as nutrients; 5. Clean water is returned to the aquarium.

  • As fish eat and grow, they produce waste that contains ammonia.

  • A built-in bio-filter converts ammonia into nitrates as water circulates through the system.

  • Nitrates move upward into the planter box, where plant roots are exposed to the water.

  • Plants use these nutrients to grow, helping remove excess compounds from the water.

  • Filtered water flows back into the tank, supporting a cleaner, more balanced environment.
