Scrape it off with a razor blade

Glass or acrylic tank?

 

[Bethany]

take a clean cloth and just wipe it off

brillo pads if it's really caked on

Oh yeah! That'll work good to scratch the **** out of it!

if needed just use a razor blade as stated if it is glass, if it is an acrylic tank it may been to polish it.

i said brillo pad, not steal wool, not even close to be as abrasive. i use them all the time, and not one scratch

The 40Long I just bought had the same problem, but my algae scrubber and a quick wipe with an aquarium wipe took care of them.
