calcium deposits

I just got a used 75. The guy let the water evaporate over some period of time and the glass
is coated with calcium deposits. His water must be 1000ppm. Anyway does anybody know of a product that
I can use to get rid of it?
Thank you
Jay

Someone here, I wish I could remember who so I could thank him, recommended Barkeepers Friend. You make a past out of it and rub it on the glass as though you were waxing your car. Let it dry then buff it off like you would wax. This stuff is amazing. Some of my tanks are 20 years old and they haven't sparked like this since they were new.

Just sharing Barkeepers friend.
