My TA is too High at 190-200, I used pool calc to lower PH from 7.8 down towards 7.1. I have added the correct amount of MA per calc. PH doesnt seem to move much. Should I keep going? My PH seems stable. I thought TA acted like a buffer for PH swings? My TA is suppoed to be at 60-80.
TA too high

well i cant remember the exact amount the calc said approx 16 oz. or so i think? My numbers are at home. I'm pretty sure my PH was 7.8 according to the taylor basic OTO test.
I get 27 ounces of 30.45% of MA to move your 4545 gallon pool (with a starting TA of 200 ppm) from 7.8 to 7.1 ph.
Hmmp, May be I have something setup wrong in my calc? I will verify the numbers I input when I get home for lunch. BTW I had to buy 14.5% yesterday to complete this task. no 29% available. Whic means now I have to double it.
Yep, then you would have needed 60 ounces...you can select 14.5% on the poolcalculator.Ame said:
How fast is your pH moving?
Yes, it is a buffer, but each pool seems to have it's own TA need, so while 70 is optimum for one pool, 100 might be optimal for another (like mine

this afternoon I put in 4 cups of MA. PH went from 7.5 to 7.1. and TA from 200 to 150. does that seem right. I have to leave it at that till im back in town
That's close, though I would have expected a bigger pH movement and a smaller TA movement.
Seems reasonable to need that much of the 14% MA to lower the pH from 7.5 to 7.1 with a TA of 200. According to the calculator, it should have required 40 oz of the 15% MA.
I too am a little surprised the TA moved that much.

Could it be the static testing error?
Playing with the pool calculator, I come up with a starting TA of 150ish for that much movement, dropping to about 110.
Or maybe I'm doing something wrong with the calculator.....

Smykowski, above you posted; (each pool seems to have it's own TA need, so while 70 is optimum for one pool, 100 might be optimal for another).
How can I know where a pools optimum TA level is?
Thanks : )

Just keep lowering your pH when it gets high, and the pool will eventually settle at its happy spot for TA.
