Hi _ I am new to the forum. Just installed a new in-ground pool this season. 29,000 gallons, roughly 18x 44 lazy-L. Using cartridge filter, and in-line chlorinator, with a Frog mineral pack.
Am targeting a lower Chlorine level - i.e. .5 ppm.
My question is what is appropriate TA level ?
Had my water tested at 82 degrees, and my results are currently as follows:
Tot Chlorine: .5
Free Chl: .5
Total Alkalinity: 75
Adj. Total Alkalinity: 66
Total Hardness: 184
From what I'm reading here at the forum, it seems all these readings are ok, but I was told I need to raise my TA to around 100 by pool supply house. To me it seems odd to raise TA to that level with PH at 7.6, as I understand adding sodium hydrogen carbonate will also drive up Ph, and then I have to add yet another chemical to bring Ph back down again.
What's the real deal here ? Is this TA too low, and what do I gain by raising it to 100 ?
