However I don't know much about them and am trying to learn about them. Whats the like top 5 led lights? What do I look for with leds? I was planning on the Hydra. I see they have 2 options. 52 and 26.? Any help/advice is much appreciated =) I want to be able to put/grow what ever I want in this tank.
