Water Balance: Adjust alkalinity first, then PH . . . Or Not

[PoolDoc]

0.2 pH units isn't much -- a pool will vary that much from day to day, just because 'it want's to'!

TA is bit low; you can add a box of borax and raise both pH and TA a bit. Or, you can add a box of baking soda (5 - 10 lbs) which will mostly raise TA.

I've tried to avoid getting rigid with the numbers -- there are many, many combinations of values that will work. Being very specific about what your numbers MUST be is easier to understand, but harder to carry out.

We've opted to make your brain work more, so you can work less on your pool!

So you are thinking a whole 4# box of borax? Any ideas on how much it will raise each of them?

**EDIT** Actually, I just added 4# of baking soda. I think I will test later tonight and perhaps add another box of either baking soda or borax.

AHHH HAAAAA!!! Mind blown... Thank you very much.

I hope "AHHH HAAAAA!!! Mind blown" was a good "mind blown" and not, "oh, no, now I am more confused than ever!"

All good! added 8# total baking soda. Will test tomorrow evening.

Did you test TA after adding the first four pounds of baking soda? What was it? What was the pH?
