"she said I needed to get calcium in right away or the water being to hard would rust/eat my pump up along with my metal.... guess not?"

Correct! She was SO wrong she was contradicting herself! Adding calcium makes the water HARDER not softer. (that's why the test is called "Calcium Hardness") And hard water causes scaling that damage metal. It's usually water that's too acid or too alkaline that eats metal.
