Does anyone have a clue on how to do it? I have two used 20 gal and one used 50 gal tank that all have lime build-up on them. I've been having a devil of a time trying to remove it all. It's so bad on one that most of it is cloudy; can't see the animals in there very well at all!
Thanks for your help!
