I was caught off guard by my CH levels. I didn't know I lived in an area with hard water and now my pool, just filled, has a CH around 1000. I need to check again, but I'm pretty sure it's the same coming out of the tap. Aside from draining and bringing in 1,000,000 bottles of arrowhead mountain spring water are there measures that I should be taking to keep this in check? I read somewhere that I should keep PH around 7.4 to help with scaling.
