I just swapped out the fake stuff for some REAL PLANTS!! Also, thanks to something I saw from mrmalta, I added a black background, just to see what it looks like. I think it's pretty cool. All I did was cut a black plastic trash bag to the right size, and it stuck to the back of the tank with static cling! I found that out by accident
I also changed the light bulb to a new 18,000k.
