I just looked at your thread title: I'm afraid that with a CH of 700, "easy" may be out of reach. I think the best we can offer is "easier".
Anyhow, as a starting place, test pH, TA, and CH on your well water. Post those results.
It's possible to drop out calcium, but it may be easier to dump and refill, depending on what's coming out of your well.
Also, you need to get yourself some distilled water from Walmart, before you test CH again. Mix 1/4 cup pool water with 1/2 cup distilled. Mix and test. Multiply the result x3. It's easier that way, and saves on calcium reagent.
