simplifying aquarium care

Aquatic Circle was developed to apply aquaponic principles to real aquariums through hands-on testing and practical design.

why this system was developed

This video shows an early development setup used to explore how aquaponic principles could be applied to home aquariums. It reflects testing and experimentation that informed the final production design.

The production version of Aquatic Circle has been refined for everyday aquarium use and is designed to work alongside responsible aquarium care.

    Founded Aquatic Circle LLC

    October 1, 2021

    During the pandemic, Minh discovered a love for fish tanks. Inspired to find a better solution to aquarium filtration, he designed his own aquaponic filtration system.

    This first successful design became the foundation for Aquatic Circle.

Adjacent to it is a 3D schematic of the tank's structure. Below that is a more detailed fish tank with colorful fish and aquatic plants labeled 'Version 3.' To the lower left, there's a photo of a different fish tank setup with equipment on a windowsill labeled 'Version 5.' Lastly, there are two gray 3D sketches of the tank's early filter designs, labeled 'Version 4' and 'Early filter design.'
