This is my first post but have been a lurker for years... TFP has been such a help over the last 6 years of pool ownership. So thankful for you all...
~20k gallon pool was replastered this past summer. PebbleSheen finish which is great... love it.
Current readings:
FC 3.5
TC 0.0
PH 7.7
TA 70
CH 140
CYA 40
My PH is almost always stable at 7.7. I am only adding chlorine weekly (maybe biweekly now that winter has taken hold) at this point. We do use the spa. Rather than funding MA to drive ph toward 7.4 I’ve resigned myself to letting the pool be where it wants at 7.7. I can get it lower than 7.7 but it seems to want to rise up to 7.7 and wants to stay there. I’ll likely revisit where I let it stay this next season.
Here is my problem since the remodel:
I have not been able to increase my CH. It’s been as low as 120 and have never really seen it higher than 150. I’m not doing any water additions other than rain at this point. I’m having a hard time understanding why I cannot increase my CH despite adding about 75 pound of calcium chloride over the past 5-6 months. I’ve just added 25 pounds of calcium chloride this weekend and the test only indicates a movement from 120 to 140. I’m also using test strips to read the CH in case my test kit isn’t accurate. The test strips indicate the same reading. I obviously have concerns about keeping a low CH level but am unsure how to move an otherwise stubborn pool.
Any advice? Should I not be this concerned? Thanks in advance!
