I want to start a planted tank but... Well I tried it once and my tank crashed. I right now have a 20 tall, I am upgrading to a 56 column, but I might only try with a 5 gallon lol. What do I do? Can flourescent lights work? If not what about LEDs? Do I have to use fertilizer? And what about co2? I really cant afford nor do I want to use it! HELP!!!
