I have source for the reflective material if any of you guys want to go in a get a sheet? a 4'x8' sheet would be around 175.00 and I have a set of drawings that will yield 8 reflectors close to the originals with that one sheet Jason did a good job on those I have made several like those and they do work extremely well . I have one on my frag tank that is 38" square. the one on my 156 is elongated to 60"
