Watched a video about par loss due to specific color backgrounds. Currently looking for a background for my 150. Not having much luck finding one that size. What do you all do for the back of your tank? Paint? Printed backgrounds? Post pics and good places to get some.
I use construction paper from walmart which is water repellant and a dollar per large sheet. If I go to sell the tank, It is is easy to remove or the buyer can remove if they wish to change the color
