Thanks guys :)
Raye, I find it funny that you say that because I had so many issues with it when I first started off. It would die off slowly, but now it's growing like weeds. I had to tie it back down to the driftwood because it was taking over the tank!
Muchumouse, I use 25w clear bulbs. I used to have the 15w ones, but they weren't enough for the plants.
