One of our most asked questions is, which LED Aquarium Light should I get? In this quick guide I'll give my recommendations. Definitions: Low light = Undemanding plants, Anubias, Crypts, etc. Medium Light = Stem plants and most other plants that aren't carpeting High Light = Can grow virtually anything, really does best with co2 added.
