    Adding more than one chemical

    Any restrictions on adding pool chemicals when several are needed. Example: you need to acid & bleach & baking soda. All at once ok? I usually add acid, wait 10 minutes then bleach then B soda. Need I wait?

    You should wait at least a few minutes between chemicals. The only major restriction is to not add CH on the same day that you add anything that raises the PH (PH Up, soda ash, washing soda, borax, baking soda, shocking, etc).
