Hard water in Arizona

[Steve H]

Having lived in AZ for almost a year now, I've heard the water in this state is very hard, hence the reason for RO systems, How are the AZ folks here dealing with this issue for their pool water?

Yes, plenty of CH, salt and often TA in your tap water. The best way to manage your pool is by managing CSI. Keeping your CSI between -0.3 and 0 will allow you to manage CH levels well outside of TFP recommendations. We have plenty of desert folks managing pools with CH above 1000 ppm. PoolMath will give you the number, tweak PH and TA to change the CSI. You will likely want TA around 50 and pH at 7.8.
