Soak it with a stronger concentration of vinegar.

Hydor makes a powder designed to dissolve coraline algae and calcium on pumps. There isn't enough to soak the tank entirely, but there should be enough to turn the tank on the side and cake it on.

CLR if the vinegar isn't enough.

a razorblade always works for me.

I think I am first going to turn the tank on its side and soak it with 100% vinegar. Before I filled the tank half way with water and filled the rest with vinegar and it did not work well. Then I will try the others if it does not work. THANKS guys for the input!

vinegar works for me. 2/3 vinegar and 1/3 water

If the calcium build up is really bad it will start to etch the glass and neither vinegar nor CLR will get rid of that.

for my last tank i had to resort to soaking paper towels with straight vinegar, placing them on the area, and then wrapping with plastic wrap so the vinegar didnt evaporate over night. it still took some razor blade work but even CLR wouldnt take this stuff off.
