When ordering PLEASE READ AND ADD A NOTE DURING CHECKOUT: Please take a precise inside width measurement of your actual aquarium so I can cut these to the proper size. I've encountered some variance from tank to tank and don't want you have to have any issues during installation. The best way is to take a tape measure and determine the distance from the inner wall to a midpoint in the tank, applying a piece of masking tape or marking that spot with a sharpie. Then measure the opposite half, combine the numbers for a total inner width. Measure twice to double check your work.  This page lists the common widths, but the baffles need to be a little less than the inner width.  If the baffles are wedged in and are too tight, it could crack the tank.  Enter the inner width in the comment field when you place your order and I'll make cut them accordingly, 1/8" less than YOUR MEASUREMENT.
