Day 20 - A new background

Here's what it looks like now. The Cabomba has grown quite madly, about 3 inches in a week even without CO2, thought its looking a bit yellow. Lilaeopsis Brazilensis is starting to branch out too, but not as fast as I'd like it to be. For the week that my CO2 tank was being refilled, some black beard algae started growing on the Echinodorus Amazonicus and some green spot algae appeared on the glass. Cleaned off the green spot algae, hopefully the black beard algae will go soon too.
I've added a blue-tone background and bought 3 more plants: the Tiger Lotus Lily on the mid right, Anubias nana in front of it and a reddish plant at the mid-left, not sure of the name of it for now.
Sorry about my photography skills... not much space between the front of the tank and the wall in front of it =p
