Hi, I am looking at taking the leap into my first Co2 tank. I am wondering, do any of you know of an online article or resource which is a Co2 info source for a totally ignorant newbie to the Co2 world? I really know nothing about the practical application of Co2 and what I will need to purchase to make it work, but I have a strong desire to learn. To give you some idea of what my Co2 needs will be: I'm looking at setting up approximately a 20-35 gallon tank 'high-tech' with Crystal Red Shrimp, a shoal of peaceful fish, heavily planted, with some demanding plants. I only have experience with a low-tech setup.
