How would be the easiest way to clean a cast iron fry pan that has been heated with water in it that had calcium in the water as now it has calcuim deposited 1/8" thick?

It's probably not calcium (a fairly reactive metal) but a salt. Try leaving it with diluted vinegar in it overnight.
It a reasonably weak acid which would not react much with the iron.

The old fashioned way is to toss it in a campfire, then re-season it when it's cooled. Whether or not it's coated in calcium or salts, fire should solve this problem.

How to clean cast iron fry pan

Start with the vinegar soak. Then use a wire brush to get down to bare metal. The best being a cup-brush in a hand-held power grinder, or lots of elbow grease with a regular brush and/or metal scouring pad. Then wash as clean as you can get, soap is OK at this point.

Once you've cleaned and dried it, coat it with a thin layer, less than 1/8", of high temp oil like canola or peanut and put it in your oven on fairly high -- just below where the oil begins to smoke if you can -- and let it sit for an hour. Then cool and wipe out the excess. You may need to repeat the oil treatment after each use until you get a nice non-stick finish.

I re-season pans on the stove top by heating oil until it starts to smoke and then cooling. For some reason I also put regular table salt in the oil, but I think this may be an "old-wives" thing -- maybe more for a cleaning abrasive scrubbing process.
