Add Sodium Bicarbonate and Chlorine/shock together?

[atdale]

Attached a pic of my readings from SureTREAT app (sorry folks, I prefer it to pool math). I thought I remembered reading recently that shock should be added in evening and SB added in the morning, but never together - is that correct? First time poster but have been searching and reading for awhile!

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 Levels

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.
