High ch, 460, in Arizona. Try to keep CSI low to prevent scaling. Keep PH at 7.2-7.5, TA at 60-75. I can keep it in balance, but as I add muriatic acid to keep PH under control (it has a tendency to rise even though water feature is not run often and low bather agitation) which lowers TA. So then I have to add baking soda to raise TA and then acid to lower PH. Vicious cycle. Is that just the way it is or am I doing something wrong?
CYA 50, FC always within range. No other issues.
