I've been doing this about 10 weeks - feel like I should have this down by now, but don't.
I get one thing in balance, and then something else goes out of balance. I have a SWG system, so I've been playing with pump run times for FC and pH. I'm not doing it very well.
Here are today's numbers:
water temp: 79 degrees
FC 8.5 levels had been pretty steady until about a week ago;
FC dropped to 3, so I added bleach to support the salt cell;
FC up to 7 (ok..., that seemed to work);
a few days later, FC dropped to 1.5; I added bleach;
FC up to 9.5, lowered pump run time by an hour (now 9 hrs on low);
2 days ago, FC still at 9.5, dropped salt cell to 95%.
today FC 8.5; lowered pump run time by an hour (now 8 hrs on low)
pH: 8.2 (had been sitting very nicely around 7.5)
TA: 90 Pool Math says to add 62 oz of MA to lower pH to 7.2; then aerate to raise pH back up to 7.5)
CH: 375 I was shooting for 350 which always seemed to get a better CSI on Pool Math; it seemed to take me forever to raise up the CH. Some weeks I would add calcium increaser and there would be no budge in the numbers, sometimes even dropping. A week ago, it was at 275, so I added enough for 350, and now it's a tad too high. Do I wait for rain and/or adding some water when needed to lower the CH, or have I messed up and need to drain some. ( our tap water began at 75, soft)
salt level: 3200
CSI: today it is 0.47; if I met the goals, it would be -0.58. Either way, the CSI message says both have the potential to be corrosive (I think that's what it said....) Somewhere I read that a CSI between -0.6 and +0.6 is good. But then the messages on Pool Math don't show a balance until around -0.3 and +0.3 So that also confuses me.
I think I have too many questions in here. I'm sorry. This is all so confusing. Just when I think I'm getting the hang of it, then it looks like I'm bombing out.
Oh, the water continues to look great.
Thanks so much for your help and patience!!!! I'm not going to do anything until I hear back.
