Adding Baking Soda/ Calcium Chloride to Pool w/SWG

[Paul Evert]

Using the pool math app I want to increase my TA from 37 to 70 by adding baking soda. Next, Increase CH to 350 from 186 by adding calcium chloride. Do I need to turn off the SWG while adding the baking soda and calcium chloride?

Can you post test results from your TFPro? The TA and CH levels are numbers you can not get with a proper test kit.

What is your pH?

If Marty doesn't mind... I'll elaborate.

Paul, we can tell from your test result numbers that you probably got those results from a pool store, or some other source other than your TF-Pro. We don't base our advice on pool store test results, because they are well-known to be anywhere from somewhat close to wildly inaccurate. You will not get better test results, from anywhere, than you can get on your own with your TF-Pro, which is why we really only trust those.

Further, our advice is also based on an overview of all or your test results, because they can affect each other. Which is why Marty is asking about your pH and asking for your TF-Pro test results. What he's after, to give you the very best advice, is the results of an entire suite of TF-Pro test results. And you can make it easier on us to read them if you return them in this exact format:

FC: xx
CC: xx
pH: xx
TA: xx
CH: xx
CYA: xx
Borates: (If you use them) xx

With that, Marty will analyze the whole picture and advise accordingly.

Ok, I understand the importance of accurate test readings. I have been using those provided by a pool store while waiting for the TF-Pro. I’ll post new numbers once the test kit arrives later this week.

To elaborate a tad further- It’s highly likely that the pool store ta result is really “adjusted” ta & that your actual ta is higher & you may not need any baking soda at all.
The pool stores really love to sell expensive baking soda!
Waiting a few days won’t harm anything.
Looking forward to seeing your tfpro #’s.
