Time between adding dry acid and chlorine

[mochidis]

Total newbie here. Vynl pool....I'm using dry acid
(sodium bisulfate) to bring PH down before SLAMING. How long do I have to wait after adding dry acid and high levels of chlorine?

Welcome to TFP.

15 minutes will do. 30 minutes is more then enough.

Note that continuous use of dry acid is not recommended for many pools. Read Acid - Dry Acid

Thankyou! For some reason I thought the wait time was longer in between sodium bisulfate compared to muriatic acid. Same timing, 30 mins, right? mind, I thought that because dry acid in powder form instructions said to circulate for at least 4 to 6 hours.

I have never heard if that.
