what about turning the tank around,if at all possible ?
and just have tall plants at the back to hide it,
if you ...
Try using baking soda and ammonia in a thick pasty mix with some sort of scrubber. It works to remove lime scale and even odors in sinks and when i used it the chrome was even polished without scrubbing.
If I scrubbed it with a scrubber, it'd scratch. It's a glass tank btw.
I tried using a razor blade, and actually, it looks like there was something taped onto the tank. Maybe a background? Anyway, it was sticky when I moved the blade across the more heavily effected areas. What do you suggest to remove stickiness cause by tape?
Duct Tape! the absolute best sticky remover out there! Take about 6 inches of it, make a loop and use your hand to push it against the sticky areas and peel it back. If that doesn't take it off then just be pateint and use the razor blade and eventually it will all come off.
I have used it to removed most tape adhesives, that blue putty for posters, stuck on old Duct Tape, the adhesive that stores use for the labels on pots and pans, super glue on linoleum, hot glue on counters, and many other things. Can't hurt to try.
API makes a product that is aquarium safe. I can't remember the name of it though. Also there is a product called Goo Gone that may help. It is very aromatic and you may want to turn off the air to your tank when using it as I don't know how it would affect the inhabitants of your tank.
