Aqua One Tube Marine Blue 20W 23.5in T8 (620/850/700/880)

Marine Blue tubes recreate natural light found at ocean depths, emphasising the florescent clours of your fish whilst aiding certain marine invertebrates in the photosynthesis process. Aquarium light tubes will lose their intensity gradually over time. It is recommended that you replace your aqua one light tube and starter every twelve months to maintain a healthy aquarium.
