Lowering Alkalinity

[Walter2050]

5 month old pool owner here . Been working to get my alkalinity down to try to stabilize my ph . Always having to add acid
Just read my readings and I’m at Fc 3.4 ,Alk 80,ph7.8,ch 250 and ca is 50 . Water temp is 90 here in Texas
For the first time I just checked my auto fill water from my hose bib and it’s showing 210 for alk and 7.6 for ph
Is that pretty standard for the pool fill readings? And am at a no winning situation trying to get alkalinity down ? I already tried lowering the ph to 7.2 then aerate . But can’t seem to get alkalinity to 70 and stay

Yup, hard to keep TA down when you have 210 fill water.

If you don't have a SWG then keep your CSI below 0 the best you can through managing your pH and TA.

That what I’m working on . Did my csi and it was 0.12

Is there any kind of filter I can put inline on my auto fill to make the alkalinity any lower ?

0.12 is ok and if you can keep it there it may be the best you can do.

No, TA is not something that can be filtered.

TA is something like the carbonation bubbles in soda. You can't filter that out.

Thank you sir

I know you didn't ask, but if ca here is CYA, then your FC is too low.

Yes sir thank you . I raised it to 7ppm
