I live in Southern Califormia and have a 12K gallon fresh water pool, healthy and no problems that I know of. I use liquid chlorine and liquid MA, the cheap Home Depot stuff. Typical pool chemistry before I add Cl and acid about every 3 days:
Cl 3.0
Ph 7.6
I check TA & CH once a month, most recent readings:
TA: 100
CH: 575
It's the CH that concerns me of course. My understanding is that 400 is the recommenced max. In February it got up to 525 and so I drained ALOT of water and managed to get it down to 350. I say ALOT of water because my tap water itself is 275. So draining/replenishing was a big time consuming PITA. But obviously I have to do it again after a brutal summer with lots of evaporated/added water. However I'd like to wait til the heavy winter rains come in a couple of months.
On the one hand I understand the problems high CH can create and so maybe I should deal with it now. But when I use my Taylor Watergram calculator and dial in the readings and water temp (60 degrees), it says my saturation is at .3, within the acceptable range of pool balance.
So the way I'm interpreting the situation is: 575 is not good, but considering the other readings, I'm still OK for now --- the water is balanced in spite of the high CH --- so no need drop what I'm doing and take immediate action.
Do I have it right?
Thanks.
