thanks Jeff ! I have about 18 inches between the wall and back of my aquarium. where would I be able to buy vinyl for my tank? is it a certain type made for aquariums or can I just get vinyl laminate from hd or lowes
greg a sign store should be willing to sell you what you need it's used for sign lettering
This.
It's cheap too. Use lots of soapy water to apply it, like lots lots, it will allow you to get it on the tank and slid it around and then use something like a credit card to start in the middle and work all the air out, gives you some wiggle room.
I use black vinyl over white for my bedroom windows for 100% light blockage. I work night shift. Window looks white from the outside, but pitch black on the inside. Was pretty easy to install.
