how long do I have to wait between balancing ph and slamming with chlorine

[CamiS]

I replaced 1/2 of the water in the pool (lowered CYA to 50) and I want to SLAM it. I balanced the ph & alk 1 hr ago (soda ash) , wondering how long do I have to wait before adding the liquid chlorine to slam FC level?

Test pH to make sure you're close to 7.2, then SLAM away.

You want to avoid pouring Muriatic Acid and Liquid Chlorine in at the same time. About 15 mins between them. Otherwise no need to wait longer for most chemical additions, and most other ones can be done simultaneously.
