Choosing the Right Fluval Plant 4.0 Light

When choosing a Fluval Plant 4.0 light, consider the width of your aquarium, the type and density of plants being grown, and the amount of light required by your aquascape.

Smaller and lower-demand planted aquariums may only require a Nano or lower-wattage model, while larger tanks or heavily planted aquariums may benefit from a higher-output Plant 4.0 or Plant Pro light.
