ta going down, ph going up

[staberg]

hi all, i have a 3 week old plaster (wet edge) pool. my ta reading at fill time was 200 and the ph was above or at 8.2 (the highest on my kit...im waiting on a t-2006). i've been adding some acid to lower both. as of now, the ta has come down to 70. the ph will come a little, but then climbs back up to well over max. i understand the relationship with new plaster and rising ph, but what is the best approach? if i try to lower the ph more with acid, won't it just keep bringing the ta down as well? or at this point is it a waiting game until the plaster cures...thanks

During the first three or four weeks after applying fresh plaster you need to focus on keeping the PH in range, which is 7.2 to 8.0. The PH can raise very rapidly and will typically require acid additions every day during the first month. After that things will slow down dramatically and you can focus on things like TA level.

thanks jason, so i should focus on my ph level first, regardless of where the ta goes?

 

[JasonLion]

Correct.

sorry, one more thing...how will i raise the ta without also raising the ph?

Why do you need to raise the TA? You use baking soda and it has a minor effect on the pH.

cool...didn't know about not having a target ta, but will adjust ph and just let ta kind of do it's own thing according to the ph...it's just with a new pool, i didn't know which should take priority.
