This short presentation tells the story behind the design and intended use cases of the PP tank indoor RAS fish growing system. You'll see a complete walkthrough of this automated feeding, eco-friendly recirculating aquaculture system, including how it maintains water quality, enables high-density fish farming, and supports species like tilapia, catfish, and trout. We'll demonstrate the key components—drum filters, biofilters, and real-time monitoring—and explain how this system saves over 90% of water while providing a controlled environment for urban aquaculture and high-value species cultivation.
