since taking over my pool in june i've been constantly cognizant of pH, as i have a good deal of scale around the waterline as well as constant buildup in the salt cell...since the water has gotten colder though, with my very high CH (at least for now until we get our rocks repainted and do a water exchange at that time), my CSI seems more balanced at a higher pH. example: this morning, with pH at 7.9 my CSI is 0.09 (at 7.8 yesterday and the day before it was perfect at zero). last week, right after i had added acid to get it down to around 7.4, it was -0.43.
so my question is, should i be worrying more about keeping the pH in the mid 7s or the CSI? normally right now at 7.9 i'd add acid and take it down to around 7.4 or 7.5, but with the CSI number where it is i'm not sure if that's the wise move at the moment. any suggestions or advice welcome...
