Which tanks is it best for?
The S3 Plus suits planted nano and small aquariums where you want strong, even light in a slim fixture, ideal for low- to medium-light plants such as Anubias, Cryptocoryne, Java fern and easy stem plants. The step-up S3 Pro+ adds a 10000K tuning; for demanding plants add CO2 and dosing. See our planted aquarium lighting guide.
How to use it
Mount the light across the tank on its brackets and run it 7–8 hours a day for a planted tank, ideally on a timer. Always give the tank a dark night period and keep it out of direct sunlight to avoid algae. See how many hours should aquarium lights be on.
