I am new pool owner in Fremont, CA with some questions. I have a 16000 gallon, plaster, in ground pool with SWG and solar heat.
Test results first:
Do I have to replace most of my water to lower CH? If so, do I need to hire a pro or it's a DIY job? It's pretty dry in bay area, do I need to worry about pool popping if I drain most of the water?
