Tunnel Aquarium
Tunnel aquarium projects from Pureflow Bio bring acrylic viewing, exhibit planning and life support together. Work with a manufacturer and systems team in Mysuru, India, to define the tunnel geometry, water conditions and installation scope.
What is Tunnel Aquarium?
A tunnel aquarium is an aquatic exhibit with a visitor passage beneath or through a water-filled display, using engineered viewing panels and supporting structures.
Tunnel Aquarium applications
Public aquariums and oceanariums
Best for immersive exhibits with a defined structural and life support design.
Visitor attractions and institutional projects
Best for coordinated display, visitor circulation and facility planning.
How Tunnel Aquarium projects work
Develop the concept
First, define the viewing experience, species, water depth and visitor passage.
Engineer the interfaces
Next, coordinate acrylic panels, joints, supports, waterproofing and life support connections.
Install and commission
Then, complete the agreed assembly, inspections, water testing and operator handover.
Tunnel Aquarium features and benefits
Integrated viewing and treatment
Coordinate the display with its life support plant and service routes.
Custom acrylic arrangements
Review curved sections and joint positions against the approved design.
Repair and renovation review
Provide drawings and condition photographs before agreeing repair work.
Planned maintenance access
Allow space to inspect panels, seals and concealed service connections.

Tunnel Aquarium project specifications
This is a project-specific configuration. Project dimensions, materials and engineering interfaces are agreed in the approved drawings. Confirm the current drawing, component datasheets and duty in your quotation.
| Selection item | What the quotation must define |
|---|---|
| Tunnel shape and clear viewing dimensions | Confirm for the proposed application and selected configuration |
| Operating water depth and species | Confirm for the proposed application and selected configuration |
| Structural drawings and building loads | Confirm for the proposed application and selected configuration |
| Visitor route and emergency access | Confirm for the proposed application and selected configuration |
| Delivery route, lifting and assembly | Confirm for the proposed application and selected configuration |
Configuration and supply details
Confirm materials, connection standard, dimensions, electrical requirements and included components for the selected equipment. The quotation defines current pricing and the approved scope.
How to select Tunnel Aquarium
Acrylic thickness, joints and supports require project-specific structural engineering; tunnel length alone cannot establish a safe design.

Tunnel Aquarium installation and maintenance
Installation and integration
Agree foundations, supports, waterproofing, lifting and building access before fabrication. The quotation identifies engineering approvals, testing and commissioning responsibilities.
Routine maintenance
Use approved acrylic cleaning methods. Inspect joints and accessible supports, and request an assessment of scratches, leakage or damage before attempting repairs.
Warranty, dispatch and installation
One-year equipment warranty
Confirm coverage and operating requirements in the quotation.
Project schedule
Design, fabrication, installation and commissioning dates are agreed for your project. The equipment-only dispatch term does not define the complete project schedule.
Made in India
Manufactured by Pureflow Bio in Mysuru, Karnataka. Installation, commissioning and service across India are agreed for your project.
For complete turnkey projects, confirm the project schedule, utilities, site preparation, installation and commissioning responsibilities separately.

Tunnel Aquarium FAQs
How does an aquarium tunnel work?
Visitors walk through a curved acrylic tunnel set into the floor of a large tank, so fish swim around and above them. The acrylic carries the water load, while a hidden life support system keeps the water clear.
How thick is the acrylic in a tunnel?
Thickness depends on water depth, tunnel span and the acrylic grade, and is set by structural calculation for each project. Tunnels under deep water use very thick panels. We confirm it in the design for your exhibit.
Is a tunnel aquarium safe?
Yes, when it is properly engineered, fabricated and installed. Acrylic tunnels are designed with large safety margins and supported structurally, and they are in use at public aquariums around the world.
Does the acrylic scratch or go yellow?
Acrylic can scratch, but scratches can usually be polished out on site. Modern aquarium-grade acrylic resists yellowing, especially when kept out of strong direct sunlight.
Freshwater or marine: what can live in a tunnel tank?
Either. Freshwater tunnels often feature large river fish, while marine tunnels show sharks, rays and reef fish. Your species choice drives the tank volume, water treatment and running costs.
What should we plan before building a tunnel?
Tank size and depth, the tunnel length and route, structural support, the plant room location, access for divers and cleaning, and visitor flow. Involve life support and acrylic design at the concept stage.
