Abstract

Submersed aquatic vegetation can survive to a depth of approximately 20% of surface water irradiance. Large displays featured in public aquariums are often open to the sky, but the building roof acts as an aperture and obscures much of the direct solar path. Side-walls within the tank often absorb more than they reflect or scatter and as a result plants and fish get little more than the diffuse solar component without supplemental illumination. The loss mechanisms are detailed and design suggestions are considered, including heliostats, lightpipes and tracked parabolic reflectors with fiber optics.
