ATL's conventional tunnels are available in 1.8m and 2.4m radii, in straight or curving format, simple 180 degree semi-circular section or with extended vertical 'legs' to offer a bigger view.
The modern ocean aquarium 'must have' is a walk through acrylic tunnel but often these are large, intrusive and very costly features. Identifying these drawbacks ATL choose to offer two 'standard' forms which represent great value for money and afford the visitor astounding views of the underwater world.
For the ultimate experience we also offer a 270 degree acrylic tunnel that gives clear viewing from floor level to overhead.
