We are looking at getting a 55g tank soon. I will be doing a fishless cycle with it. I have a few questions. It comes with a double filter, will I need another on or is this one good? Also, I do want to put some live plants in it. What kind of plants are good, and where do you get them? I found a LFS in my area, but they don't have anything like that. They only guarantee their fish for 24 hours.
