My neighbors must think I'm crazy. I have polarized glasses and three d glasses mixed with my phone, a tablet,and a PC...I keep bobbing my head up down left right. I tried all sides of the tank, non tinted car windows,and two different windows in my house... I don't see a difference when looking through any of the items. Can some one advise me on what to do so I can stop looking like a creep by holding electronics behind panes of glasses while changing glasses...the only time I noticed something different was when I looked through my tinted windows at other peoples windows.it looked like an oil spill...and I called again and they can't help me. Tank is a fifty gallon breeder..thanks!
