Hi all, I’m still learning about my pool, but I’ve always been able to keep chlorine and pH perfect but they alkalinity has always been low, I finally decided to tack that this week and I added the correct amount of baking soda to raise the TA, but now my pH has gone way down. I’m reading that soda ash cannot he used in a fiberglass pool, to use baking soda instead, but won’t that make my alkalinity too high? Help please

If you added baking soda, that raises your TA and your pH. pH by only a little.
I see you do not have any tests saved in your Poolmath logs. Either save your tests there or post one here. From your own test kit.

I just added my levels from today, I didn’t know that connected to my account, thanks for the tip!
A random website, I wasn’t sure of how accurate it was, which I why I posted here

What was the pH and TA before you added the baking soda?
How much baking soda did you add?
What else have you added besides the baking soda?
If you only added baking soda, the pH would have gone up, not down.
TA was 40, pH was 7.6, I added 7lbs of baking soda (9000 gallon pool), and that’s it. Originally the pH went up too high (8.0) and I was thinking we would need to bring got down with ma, but we had a lot of rain yesterday and last night so I checked it again just in case and it was down to what I recorded today
When you got the sample, you probably got a lot of rain water. Allow the water to mix by running the pump and brushing the pool and then retest everything.
