I have a background that came in blue on one side, black on the other. I have had the blue up for the last year, but I'm thinking about changing it to the black side. (I love the balck bg on the readsea tanks and Im starting the think it makes the corals/fish pop more). The trouble is my tank is within 2 inches of the wall so it would be a tight squeeze to get behind there. I used olive oil to apply it the first time and a credit card to smooth out the bubbles. This was when the tank was empty and I have a ton of space to work with of course.
Anyone have any ideas on how to swap it to the other side without having a ton of bubble between the background and the glass?
