Time between chemicals

[aquam4n]

I've seen on here not to take store advice, do you have to wait in between chemicals for a time period or can you add all at once?

Depends. You should not add chlorine and acid right after each other. 15 minutes or so between them with pump running.

You should not add baking soda/soda ash/borax and calcium at the same time. What a day in between.
