I agree with everyone that said calcium is controlled by a water softener.
I would think of calcium compound buildup is that fast it would be a
problem in pipes, including the water system pipes.

There are fixes for iron in the water. This has a lot of information:

Gentlemen do not get confuse between calcium and silica that we see on the
pipes faucet deposit 90%
of time it is silica which is very hard to get ready of. Take sample of you
water to lab and get it analyzed.
