Anyone have an easy way to remove what I believe is hard water spots, or calcium buildup? Someone gave me a 55 gallon for free today but it was in pretty rough shape cleanliness wise, i gave it a good scrub down with some hot water but there are quite a few stains left in the glass, Im not sure if there is even a way to remove them, anyone else had success with something like this?
