Reducing calcium hardness

[JerryZ]

Theoretically though would it possible to increase the pH to around 9.5-10, vacuum out the precipitated calcium, and restore the pH to normal?

If you have a SWG, and a return that comes off of it, ( pressure side cleaner, for example), you can put a fine mesh (pantyhose) on it and catch the calcium flakes.

The calcium in my fill water is 50 and ta 80 ph 7.7. Have already started the drain and fill. Working just fine
