More importantly is your lighting, making sure it is about 6500k in temperature and you have enough, if you haven't yet read over the guides byron has put up in the plant section of the forum.
Yea I read through it, I got a 29 gal from petsmart. one of the starter ones, the light doesnt have any info on it (unless i have to remove it to see it). where is it at so I could look harder?
