Aquarium light bulbs are different from ordinary light bulbs, which promote detrimental algae blooms and can lack the spectral range needed for aquarium health and visual enhancement. Aquarium light bulbs come in a range of types, spectra and intensities depending on what type of aquatic life you have and the depth of your tank. We keep UV bulbs separately. For more information, check out our article on aquarium lighting.

The color spectrum of any bulb will change with age and bulbs generally need to be changed every 6-8 months. Deeper aquariums require extra or stronger bulbs. Check your lighting fixture to find what size and wattage of light bulb you will need.
