Leaves look "burnt" red around edges
Over the past several days, some leaves on several of my different plants have developed something that makes the leaves look as if they have been singed. It's a really dark red color just at the very edges of the leaves. Some of the really skinny, tiny leaves on my one plant (I'm not entirely sure what all my plants are...) have turned completely dark red from this.
Is this some kind of algae? My tank has 8Watts/gal flourescent and no CO2. I just set up the light a week ago and plan on putting in CO2 asap. Will CO2 help fight this?
Also, I have some glosso in the mail that should be here soon. Should I wait before putting the glosso in, for fear of infecting it with whatever this is? This is my only tank, so I don't really have anywhere else to put the glosso...
