Along with adding co2 a week or so ago, there's a few other changes to the tank.
First, the hardscape situation: I never really liked the right side of the tank. If you look in the past pictures, there's always been this little rock with java moss attached kinda thrown on that side of the tank. Totally out of place. So in October I bought that plant to put next to it. Beautiful plant, but it grew big enough to become the focal point of the tank, taking away the emphasis from the rocks and HC. I'd known that something had to be done for quite a while. Yesterday I took out the two rocks and put others in that I found in my backyard.
