I have noticed looking around on the internet that there are a lot of tanks that have a black background. I currently have a photographic background (I guess is what you call it). I am having trouble keeping the background flush with the back of the tank so it can be clearly seen. So back to my real question what can I use for the black background. I have a 150 gallon tank that is 72" long and 30" tall. Thanks for your help.
