how it works

Plants help clean the water.

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.

  • Aquatic Circle is designed for freshwater aquarium owners who want a calmer, more natural way to care for their tanks. It’s a good fit if you:

    • Are setting up or maintaining a freshwater aquarium

    • Keep live plants or want to introduce them to your aquarium

    • Want a filtration system that can serve as the primary filter on tanks up to 20 gallons

    • Want to eliminate the use of chemicals in aquarium care

    • Prefer straightforward equipment that works with established aquarium practices

  • Aquatic Circle may not be the right choice if you:

    • Are looking for a completely hands-off system with no routine upkeep

    • Prefer not to maintain or trim plants as they grow

    Aquatic Circle is designed to support freshwater aquariums and select saltwater setups through aquaponic filtration. It works best as part of a thoughtful aquarium system, rather than as a replacement for responsible care.
