Calcium Hardness

I live in southern Nevada, and use Colorado River water.

I typically exchange the water in my pool to fresh every 16 months or so. The CH is normally above 800 ppm by then and it becomes difficult to manage CSI. Learning to manage CSI is very important in our area. CSI is calculated for you in Poolmath.

More forum members in our area are starting to use softened water for their pool make up water. That removes the calcium build up issue.

My CH has been creeping up all summer. The pool is new so I expected it to but it's mow 510ppm CH & I'm getting concerned. I'll be following this thread. I'm petrified to drain any water and the dang pool float up seeing as we have a very high water table (ground water seeped into the pool during the entire build process).

You can exchange water with out draining.

Please start a new thread if you wish to get direct guidance on your situation.
