Well...I've made a pretty bad rookie mistake. I've got a 65 gallon tank all setup and filled with salt water with the peripheral equipment installing and running.....but I completely forgot about the background. My tank is about 3 inches off of the wall so there is not much room to work. Looks like I'm going to have to empty the tank to pull it out but I figured I'd ask first for suggestions. I see there are nice royal blue backgrounds out there but they involve coating the back of the tank with soapy water and all...don't think there will be enough room. Your help is appreciated!
