Add Sodium Bicarbonate and Chlorine/shock together?

Your TA is fine. No need to add. That is why we like Poolmath better, it has TFPC levels in it.

Chlorine -- add it. Follow the FC/CYA Chart
Thanks! I probably should have mentioned in the post, but i already added the SB. Too late now haha. That said, is it ok to add them together or should I wait until morning?

On the pool math app for iOS, it doesn’t seem to save my readings when I go back or hit the log addition button. I’ve upgraded to premium thinking that would fix it, but it didn’t. Am I doing something wrong?

You can add chlorine at the same time as any chemical EXCEPT muriatic acid. Wait 15 minutes or so between those two.
