I just bought an exalt tank cover for my 50 45 Ninja tank. I had hell gettin it on. Once i got it on the top wouldnt seal
Almost like it streched or somethinh
get the inside of the cover a little wet, few drops of water in it and swash it around. Then put it on the tank. The water will give you the chance to move the cover where you want it, and won't hurt the bottle or cover
