Step 3 Cut Plexiglass to fit

Now that you have your rough piece of plexiglass, you must cut it to the final dimensions. Leave the paper/plastic coating on the glass until you are totally done!!! I cut mine to about 5.25" wide and 19.5" long. Make sure that it fits snugly on the rim of the tank. As I said before, I cut my plexiglass with my bandsaw, however you can cut it with a knife. Just use the score and snap method. If you do not know how to cut the plexi, look it up.
